実験手順
To a solution of 38.5 g (0.15 mole) of N-[2-(4-fluorophenylthio]ethyl-1-methyl-ethanamine and 15.5 g (0.15 mole) of triethylamine in 300 ml of methylene chloride which was cooled in an ice bath was added dropwise with stirring a solution of 23.5 g (0.15 mole) of phenyl chloroformate in 100 ml of methylene chloride over a 15 minute period. The resulting solution was stirred overnight at room temperature and extracted with 5% aqueous sodium hydroxide. The chloroform layer was dried and filtered and evaporated to give an oil residue which crystallized to a white solid. A portion of the solid was triturated with isopropyl ether and the mixture cooled under refrigeration. The solid was collected by filtration and dried in vacuo overnight at 80° C. White crystalline product, m.p. 53°-58° C. was obtained.
