実験手順: 6.63 mL of thionyl chloride are slowly added to a solution of 1.5 g of 2-methylamino-2-phenylacetic acid in 100 mL of methanol. The mixture is heterogenous and becomes limpid after two hours stirring. The mixture is stirred for 48 h at rt then the solvent is evaporated to dryness. The crude product is diluted with an aqueous sodium bicarbonate solution and extracted with ethyl acetate. The organic phases are washed with water then brine, and dried over magnesium sulfate, filtered and evaporated to provide the desired product, which is used as such for the next step. The mixture is stirred for 48 h at rt the solvent is evaporated to dryness The crude product is diluted with an aqueous sodium bicarbonate solution extracted with ethyl acetate The organic phases are washed with water brine, and dried over magnesium sulfate filtered evaporated

実験手順: In this example, sodium ethoxide was prepared by mixing 3.0 g of metallic sodium with 100 ml of absolute ethanol. After the evolution of hydrogen stopped, a mixture containing 16.0 g of (3-trifluoromethylphenyl)-acetonitrile and 17.1 g of methyl methylamino-phenylacetate was added dropwise to the sodium ethoxide-ethanol mixture. The resulting mixture was then refluxed overnight (about 16 hours) and then cooled to room temperature. The mixture was then added to 300 ml of water and extracted with diethyl ether. The ethyl ether extract was filtered to remove precipitate. The filtrate was concentrated by evaporation affording a solid. This solid was then triturated in ethyl ether. The ethyl ether was then removed from the solid. The solid was washed several times with ethyl ether and then dried overnight affording 6.2 g of the title compound. The resulting mixture was then refluxed overnight (about 16 hours) extracted with diethyl ether The ethyl ether extract was filtered to remove precipitate The filtrate was concentrated by evaporation affording a solid This solid was then triturated in ethyl ether The ethyl ether was then removed from the solid The solid was washed several times with ethyl ether dried overnight
