실험 절차

A solution of 2-methoxy-4-trifluoroacetylamino-5-chlorobenzoyl chloride (17.4 g; 0.055 moles) dissolved in anhydrous ethyl methyl ketone (75 ml) was added little by little to another solution of 1-benzyl-4-ethylamino-piperidine (10.9 g; 0.05 moles) and triethylamine (7.0 ml; 0.05 moles) in anhydrous ethyl methyl ketone (75 ml) at room temperature. On completion of the addition, the mixture was left at room temperature and stirred for 48 hours, and then the mixture was concentrated at reduced pressure, poured into water, and extracted with chloroform. The organic solution was dried (Na2SO4) and the solvent removed in vacuo. The residue was recrystallized from a mixture of methanol and diethyl ether to give N-ethyl-N-(1-benzylpiperid-4-yl)-2-methoxy-4-trifluoroacetylamino-5-chlorobenzamide (17 g), m.p. 198°-200° C.
