Reaction Steps
A suspension of 23.6 g of N-triphenylmethyl-4-piperidineacetic acid, 16.9 g of potassium carbonate and 5.0 ml of ethyl bromide in 230 ml of dried N,N-dimethylformamide was stirred at 90° C. for 5 hours. After cooling, the reaction mixture was added with water and ethyl acetate, and the precipitated crystals were collected by filtration and washed with water to give 20.6 g of colorless crystals. Recrystallization from a mixture of methanol and tetrahydrofuran gave colorless crystals having the melting point of from 165 to 166° C.
