Triethylamine → 2-methoxy-5-{4-[1-(2-methoxyethyl)-1H-indol-3-yl]piperidin-1-ylmethy}-benzoic acid ethyl ester

Participants

Reaction Steps

Over a solution of 6.5 g (0.025 mol) of 1-(2-methoxyethyl)-3-piperidin-4-yl-1H-indole in 90 ml of dichloromethane and 3.9 ml (0.026 mol) of triethylamine, a solution of 7.2 g (0.026 mol) of 5-bromomethyl-2-methoxy-benzoic acid ethyl ester in 15 ml of dichloromethane was added. The crude mixture was stirred at room temperature for 24 hours. After standard work-up and purification by chromatography over silica gel, 9.9 g (70% of yield) of 2-methoxy-5-{4-[1-(2-methoxyethyl)-1H-indol-3-yl]piperidin-1-ylmethy}-benzoic acid ethyl ester were obtained.
