Participants

Reaction Steps

Methylbromoacetate (0.17 ml, 1.77 mmol) was added dropwise to a solution of 4-{8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene}-piperidine (0.50 g, 1.61 mmol) and triethylamine (0.45 ml, 3.22 mmol) in THF (15 ml) under an inert atmosphere. The reaction was left to stir for 18 hours. THF was removed under reduced pressure and the product purified by column chromatography on silica gel, eluting with 5% methanol/DCM. Product containing fractions were combined and solvent removed under reduced pressure to yield methyl-[4-{8-chloro-5,6-dihydro-11H-benzo[5,6]cyclohepta[1,2-b]pyridin-11-ylidene}-piperidin-1-yl]acetate as an orange solid (550 mg, 90%).
