In analogy to the procedure described for the synthesis of example 136, the title compound [(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 propyl ester was prepared from 4-[(3R,4S)-3-(4-chloro-phenyl)-4-methylamino-pyrrolidine-1-carbonyl]-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-5′-carbonitrile using propyl chloroformate instead of ethyl chloroformate and was obtained as a colorless foam. MS m/e: 510.4 [M]+.
