A mixture of 2.27 g (6.94 mmol) rac-[(3S,4R)-1-Benzyl-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-cyclopropyl-amine, 987 mg (7.64 mmol) DIPEA, 8.48 mg (0.07 mmol) DMAP and 1.27 g (7.29 mmol) 4-fluorophenyl chloroformate in 40 mL DCM at 0° C. was stirred at room temperature over night and evaporated to dryness. the residue was purified by column chromatography on silica eluting with a gradient formed from TBME and heptane. The product containing fractions were evaporated to yield 1.64 g (51%) of the title compound as colorless viscous oil. MS m/e: 465.1 [M+H]+.
