Procedure
To a cold (5° C.) solution of 2-(N-Boc-aminomethyl) azetidine (200 mg), DIEA (0.375 mL) in dry DMF (2 mL), was added portionwise biphenyl-2-sulfonyl chloride (272 mg). The reaction mixture was stirred at RT for 20 h. The reaction mixture was diluted with EA, washed with water. The organic extract was dried (MgSO4), filtered and concentrated to yield the crude product as light brown oil (295 mg, 68%) which was used for the next step without further purification.
