Reaction Steps

A stirred solution of 2-[5-[5-(4-cyanophenoxy)pentyloxy]-2-[N,N-bis(1-methylethyl)aminocarbonyl]phenoxy]-2-methylpropanoic acid (2.0 g, 4.0 mmol) in 50 mL of dichloromethane is treated with 1-ethyl-3-[3-(dimethylamino)propyl]-carbodiimide hydrochloride (770 mg, 4.0 mmol), hydroxybenztriazole (540 mg, 4.0 mmol), and ethanol (220 mg, 4.8 mmol) and stirred at room temperature over 3 days. The reaction is concentrated in vacuo and purified by chromatography on silica gel (60 g) with 40-50% ethyl acetate/hexane as the eluent to afford ethyl 2-[5-[5-(4-cyanophenoxy)pentyloxy]-2-[N,N-bis(1-methylethyl)aminocarbonyl]phenoxy]-2- methylpropanoate as a colorless foam.
