Participants

Reaction Steps

A mixture of tert-butyl 3-(3,4-difluorophenyl)-3-hydroxyazetidine-1-carboxylate (1.06 g, 3.72 mmol) and trifluoroacetic acid (3 ml) in dichloromethane (30 ml) was stirred at ambient temperature for 1.5 h. The solvent was evaporated and the crude product was purified on a Biotage Isolute SCX-3 SPE column (washed with methanol and eluted with methanol/triethylamine, 4:1) to give the title compound (0.52 g). MS m/z (rel. intensity, 70 eV) 185 (M+, 1), 156 (50), 141 (bp), 127 (58), 114 (90).
