Triethylamine → [(3S,4R)-4-(4-Chloro-phenyl)-1-(5'-cyano-3,4,5,6-tetrahydro-2H-[1,2']bipyridinyl-4-carbonyl)-pyrrolidin-3-yl]-methyl-carbamic acid ethyl ester

Participants

Reaction Steps

To a solution of 4-[(3R,4S)-3-(4-Chloro-phenyl)-4-methylamino-pyrrolidine-1-carbonyl]-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-carbonitrile (30 mg, 0.07 mmol) in dichloromethane (1 mL) were added triethylamine (13 uL, 0.09 mmol) and ethyl chloroformate (9 uL, 0.09 mmol) and the reaction mixture was stirred at ambient temperature for 3 h. After concentration it was purified by chromatography affording the title compound (20 mg, 57%) as a colorless foam. MS m/e: 496.4 [M]+.
