In analogy to the procedure described for rac-(3S,4R)-[3-Amino-4-(3,4-dichloro-phenyl)-pyrrolidin-1-yl]-[1-(1-methyl-cyclopropanecarbonyl)-piperidin-4-yl]-methanone (example 1, f) the Boc protecting group was removed. The liberated amine was reacted to the respective carbamate in analogy to the procedure described for the synthesis of rac-{(3S,4R)-4-(3,4-Dichloro-phenyl)-1-[1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-ethyl-carbamic acid 4-fluoro-phenyl ester (example 1, h). The benzyl protecting group was removed in analogy to the procedure described for rac-(3S,4R)-[4-(3,4-Dichloro-phenyl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester (example 1, d) to yield the title compound as amorphous crude brown foam. MS m/e: 363.3 [M+H]+.
