Procedure

2-(2′-Methanesulfonyl-3-trifluoromethyl-biphenyl-4-ylcarbamoyl)-pyrrolidine-1-carboxylic acid tert-butyl ester (0.97 g, 1.9 mmol) was dissolved in 10 mL DCM and 5 mL trifluoroacetic acid and stirred at ambient temperature overnight and concentrated. Redissolved in 100 mL EtOAc and 100 mL sat. NaHCO3, separated layers, washed organics with brine, dried with MgSO4, filtered and concentrated to yield title compound as an oil (0.78 g, 100%) APCI (AP−): 411.0 (M−H)−.
