Odalasvir[1] is an investigational new drug in development for the treatment hepatitis C.
Achillion Pharmaceuticals Inc’s Odalasvir (ACH-3102) is an investigational new drug in development for the treatment hepatitis C. Achillion’s ongoing study tests its NS5A inhibitor, ACH-3102, with Sovaldi in previously untreated genotype 1 hepatitis C patients over six and eight weeks of therapy. The main goal is to achieve a cure, or sustained virological response, 12 weeks after the completion of therapy.
Odalasvir is a hepatitis C virus (HCV NS5A) inhibitor in phase II clinical studies at Achillion for the treatment of hepatitis C.
In 2012, fast track designation was assigned to the compound in the U.S. for the treatment of chronic hepatitis C.

General Considerations
All nonaqueous reactions were performed under an atmosphere of dry argon gas using oven-dried glassware and anhydrous solvents. The progress of reactions and the purity of target compounds were determined using one of the following two HPLC methods: (1) Waters AQUITY HPLC BEH C18 1.7 μm 2.1×50 mm column with an isocratic elution of 0.24 min at 90:10 water:acetonitrile containing 0.05% formic acid followed by a 4.26-min linear gradient elution from 90:10 to 10:90 at a flow rate of 1.0 mL/min with UV (PDA), ELS, and MS (SQ in APCI mode) detection (method 1); and (2) Waters AQUITY HPLC BEH C18 1.7 μm 2.1×50 mm column with an isocratic elution of 0.31 min at 95:5 water:acetonitrile containing 0.05% formic acid followed by a 17.47-min linear gradient elution from 95:5 to 5:95 at a flow rate of 0.4 mL/min with UV (PDA), ELS, and MS (SQ in APCI mode) detection (method 2).
Target compounds were purified via preparative reverse-phase HPLC using a YMC Pack Pro C18 5 μm 150×20 mm column with an isocratic elution of 0.35 min at 95:5 water:acetonitrile containing 0.1% trifluoroacetic acid followed by a 23.3-min linear gradient elution from 95:5 to 5:95 at a flow rate of 18.9 mL/min with UV and mass-based fraction collection.

Example 1
Synthesis of Compound 10
Compound 10 was prepared via bromination of [2.2]paracyclophane as outlined previously (Reich, H. J.; Cram, D. J. J. Am. Chem. Soc. 1969, 91, 3527-3533; Reich, H. J.; Cram, D. J. J. Am. Chem. Soc. 1969, 91, 3534-3543). Compounds 1, 2, 6, 8, and 10 can be obtained from commercial sources. Compounds 3-7 and 9 were prepared using general synthetic methods known in the art.
Example 2Synthesis of Compound 11
A deoxygenated (argon) mixture of 9 (284.2 mg), 10 (52.3 mg), K3PO4 (248.1 mg), and PdCl2dppf.CH2Cl2 (7.4 mg) in dioxane/water (5.5 mL/0.55 mL) was irradiated in a microwave for 2 h at 80° C. The resulting mixture was evaporated under reduced pressure and the remaining solid was extracted with DCM. This crude material was purified by PTLC (20 cm×20 cm×2000 μm glass plates; eluted with 45:50:5 v/v/v DCM:EtOAc:MeOH, Rf 0.28) to give 75.3 mg of 11. The purity of 11 was determined via analytical reverse-phase HPLC using a 3.5-min gradient elution of increasing concentrations of ACN in water (10-90%) containing 0.05% formic acid with a flow rate of 1.0 mL/min on a Waters AQUITY HPLC BEH C18 1.7 μm 2.1×50 mm column with UV (PDA), ELS, and MS (SQ in APCI mode) detection. HPLC: tR 1.57 min (98% purity). MS m/z calculated for C56H64N8O6 ([M]+), 945. found, 946 ([M+1]+).

He was only in first standard in school when I was hit by a deadly one in a million spine stroke called acute transverse mylitis, it made me 90% paralysed and bound to a wheel chair, Now I keep him as my source of inspiration and helping millions, thanks to millions of my readers who keep me going and help me to keep my son happy
सुकून उतना ही देना प्रभू, जितने से
