[2-(2,5-difluorophenyl)cyclopropyl]methanol

Conditions: temp:-78.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of oxalyl chloride (1.2 mL, 13.5 mmol) in dichloromethane at −78° C. was added dimethyl sulfoxide (1.9 mL, 27 mmol) dropwise and it was stirred at −78° C. for 30 minutes. A solution of [2-(2,5-difluorophenyl)cyclopropyl]methanol (Intermediate 69) (830 mg, 4.5 mmol) in dichloromethane was added dropwise. The reaction mixture was stirred at −78° C. for 30 minutes. Triethylamine (6.3 mL, 45 mmol) was added and the reaction mixture was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure. Silica gel chromatography with hexanes/ethyl acetate (9:1) afforded the desired product, 546 mg (66%). The reaction mixture was stirred at −78° C. for 30 minutes the reaction mixture was stirred at room temperature for 2 hours The solvent was removed under reduced pressure
