Hydrochloric Acid → 5-[({4-[2-(3-Cyanophenyl)ethyl]-1-piperidyl}carbonyl)oxy]nicotinic acid

Participants

Reaction Steps

An aqueous 1 M sodium hydroxide solution (0.69 ml) was added to a THF (5 ml)/water (4 ml) solution of methyl 5-[({4-[2-(3-cyanophenyl)ethyl]-1-piperidyl}carbonyl)oxy]nicotinate (272 mg), followed by stirring overnight at room temperature. 1 M hydrochloric acid (0.69 ml) was added to the reaction liquid, and the crystal precipitated was collected by filtration. The crystal was washed with a hot methanol/water solution, and dried to obtain 5-[({4-[2-(3-cyanophenyl)ethyl]-1-piperidyl}carbonyl)oxy]nicotinic acid (240 mg).
