(Compound 1)
A. (3_ fluorophenyl) methyl pyridine _2 (IH) 1- -5_ – -one
9. 6gDMF, 45 0g (0 2mol.) Inter-fluoro-iodobenzene, 21 8g (0. 2mol) 5_ methylpyridine _2_ (IH) -.. -one, 28g of anhydrous potassium carbonate and 1. Og copper powder, 160 ° -170 °, the reaction was stirred at reflux for 20 hours, the natural cooling to 110~120 ° C, was slowly added to about 330ml 80~90 ° C hot water, cooled to 20 ° C. Suction filtered, the filter cake was washed with about 20ml of water, remove the cake, with about 300ml of ethyl acetate ultrasound 30min, suction filtered, the filter residue was washed with 20ml of ethyl acetate. The combined ethyl acetate, washed with water three times (50ml * 3), and the filtrate layers were separated and allowed to stand for 15min, ethyl acetate fraction was concentrated to a non-steamed, hot added under stirring for about 85ml of petroleum ether, cooling to 15~20 ° C insulation ~ 1.5 hours. Filtration, the filter cake was washed twice with petroleum ether (about 20ml * 2) used to give 34. 9g crude. Recrystallized from 20% ethanol to give the product 1- (3_ fluorophenyl) -5_ methylpyridine _2 (IH) – one as a white solid # 30. Ig0 Μ P.: 132 · 1 ~133 7 °.. C.
