Participants

Reaction Steps

In 150 mL of THF was dissolved 10.2 g of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-carboxylic acid under nitrogen atmosphere. To 300 mL of THF was added 10.2 g of lithium aluminum hydride, and the above THF solution was added in a thin stream to the mixture over 50 minutes under reflux. After refluxing the mixture for 4 hours, the mixture was cooled to 0° to 5° C., and 40.5 mL of water was gradually added in a thin stream thereto. Aluminum hydroxide was separated therefrom by filtration, and the filtrate was concentrated with an evaporator. The residue was allowed to recrystallize from an ether, to give 8.6 g of 2-(4-methyl-2-phenylpiperazin-1-yl)pyridine-3-methanol. Its yield was 98%.
