Reaction Steps

A mixture of 4-chloro-6-phenyl-thieno[2,3-b]pyridine (200 mg, 0.82 mmole) and ethyl isonipecotate (5 mL) is stirred and heated in an oil bath at 170° C. for 6 hours. The reaction mixture is cooled and purified on a preparative tlc plate to give ethyl 1-(6-phenylthieno[2,3-b]pyridin-4-yl)-4-piperidinecarboxylate (100 mg, 33% yield) as a colorless oil.
