실험 절차

A mixture of 3,3-dimethyl-1-(2-nitro-4-(trifluoromethyl)phenyl)azetidin-2-one (1.67 g, 5.8 mmol, 1.0 equiv) and 10% Pd/C (300 mg) in MeOH (30 mL) was exposed to an atmosphere of H2. After consumption of the starting material, the mixture was filtered and concentrated to afford 1-(2-amino-4-(trifluoromethyl)phenyl-3,3-dimethylazetidin-2-one, which was advanced without further purification. MS (MH+) 259.1; Calculated 259.1 for C12H14F3N2O.
