Participants

Reaction Steps

A solution of 2-(o-aminophenethyl)-1-methylpiperidine (8.0 g., 0.037 mole) and ethyl picolinate (5.5 g., 0.037 mole) in DMSO (20 ml.) is treated with NaH (57%) in oil (1.6 g., 0.037 mole) with intermittent cooling to moderate the resulting vigorous reaction. After 2 hr., the mixture is poured into 150 ml. of H2O and the product isolated according to the procedure of Example 25. Crystallization from isopropyl ether affords 5.9 (50%) of analytically pure 2'-[2-(1-methyl-2-piperidyl)ethyl]picolinanilide, m.p. 65.5°-67° C. (corr.).
