Reaction Steps

17.1 g. (0.1 mole) 1-Methylpiperidine-4-carboxylic acid ethyl ester (literature: J.A.C.S., 74, 3831/1952). are heated to 60° C. for 48 hours with 9 ml. (0.15 mole) 2-hydroxyethylamine and purified over a silica gel column with methylene chloride/methanol (9:1 v/v). There are obtained 9.5 g. of base in the form of a viscous oil. Yield 52% of theory.
