Reaction Steps
4-(1,1-Dimethyl-2-hydroxyethyl)pyridine [which may be prepared as described by Fraenkel et al, J. Amer. Chem. Soc. (1971), 93, 7228; 3 g] was dissolved in acetic acid (30 ml) and hydrogenated in the presence of platinum oxide catalyst for 10 hours at a maximum temperature of 37° C. and a pressure of 50 pounds per square inch, until 100% of the theoretical uptake of hydrogen had occurred. The reaction mixture was then filtered and the filtrate was evaporated under reduced pressure (15 mmHg) to give a pale yellow oil, which was then distilled (b.p. 120° C./0.2 mmHg) to give a colourless oil, which was recrystallised from a mixture of ethanol and diethyl ether to give 4-(1,1-dimethyl-2-hydroxyethyl)piperidine acetate (1.8 g), m.p. 108°-110° C., in the form of colourless crystals.
