Participants

Reaction Steps

Following general procedure B1, 4-chloro-2-(3-chlorophenyl)-6,7-dihydro-5H-cyclopenta[b]pyridine hydrochloride (0.110 g, 0.36 mmol) was reacted with methyl 2-(5-aminopyridin-2-yl)acetate (0.067 g, 0.40 mmol), followed by formation of the hydrochloride salt to afford the title compound (0.110 g, 74%) as a white solid.
