Reaction Steps

To a solution of 1-bromo-2-(trifluoromethyl)benzene (0.27 mL, 2.0 mmol) in THF (5 mL) at −78° C. was added nBuLi (0.72 mL of a 2.8 M solution in Hexane, 2.0 mmol). The reaction was stirred at −78° C. for 15 minutes then added to a solution of tert-butyl 2-oxopyrrolidine-1-carboxylate (0.33 mL, 2.0 mmol) in THF (5 mL) at −78° C. The reaction was stirred to room temperature over 1 hour, quenched with saturated aqueous ammonium chloride and diluted with EtOAc. The organic layer was separated, dried over magnesium sulfate, filtered and reduced to dryness to afford tert-butyl 2-hydroxy-2-(2-(trifluoromethyl)phenyl)pyrrolidine-1-carboxylate (I-27) as a clear oil. MS m/z 276.1 (M−55)+.
