실험 절차

To a stirred solution of 4-bromo-N-[(4-chlorophenyl)-methyl]-2-methoxy-6-methyl-benzamide (0.37 g, 1.02 mmol) in N-methyl-2-pyrrolidone (1 ml) is added morpholine (0.10 ml, 1.20 mmol) at RT. The reaction mixture is degassed and flushed with argon for 30 min followed by addition of caesium carbonate (0.49 g, 1.52 mmol). The reaction mixture is heated to 40° C. At this temperature are added tris(dibenzylideneacetone)dipalladium(0) (0.009 g, 0.01 mmol) and 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (0.019 g, 0.030 mmol) and stirred at 110° C. for 16 h. After completion of the reaction (monitored by TLC), the mixture is diluted with water (20 ml) and extracted with ethyl acetate (3×20 ml). The organic layer is washed with water (20 ml), brine (20 ml), dried over anhydrous sodium sulfate and evaporated to get the crude product, which is purified by column chromatography (silica gel, 20% acetone/hexane) to yield N-[(4-chlorophenyl)-methyl]-2-methoxy-6-methyl-4-morpholin-4-yl-benzamide (example 10) (0.11 g, 0.29 mmol, 29%). [M+H]+ 375.2.
