In analogy to the procedure described for the synthesis of example 2 (step b), the title compound rac-[(3R,4S)-4-(3,4-dichloro-phenyl)-1-(morpholine-4-carbonyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester was prepared from rac-[(3R,4S)-4-(3,4-Dichloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester instead of rac-{4-[(3S,4R)-3-(3,4-dichloro-phenyl)-4-methylamino-pyrrolidine-1-carbonyl]-piperidin-1-yl}-(1-methyl-cyclopropyl)-methanone using morpholin-4-carbonyl chloride instead of fluorophenyl chloroformate and was obtained as a colorless oil. MS m/e: 496.2 [M]+.
