To [4′-(6-ethoxy-pyridin-3-yl)-2′-ethylaminomethyl-6-methoxy-biphenyl-3-yl]-acetic acid ethyl ester hydrochloride (0.357 g, 0.736 mmol) and N,N-diisopropylethylamine (0.75 mL, 4.3 mmol) in dichloromethane (4 mL) was added cyclopropanecarbonyl chloride (0.074 mL, 0.814 mmol), and the reaction was stirred at room temperature. Once no starting material was seen by analytical LCMS, the mixture was diluted with dichloromethane and water, and the aqueous layer was extracted with dichloromethane. The combined organic layers were dried over magnesium sulfate, filtered, and concentrated, and the residue was purified by silica gel chromatography (ethyl acetate in hexanes gradient) to give the title compound.
