실험 절차
To an ice cooled solution of tert-butyl 3-((4-fluoro-2-methylphenyl)(methyl)amino)azetidine-1-carboxylate (D33) 8170 mg, 0.577 mmol) in dichloromethane (1 ml) trifluoroacetic acid/dichloromethane (3/1 ml) was added and the resulting mixture was stirred at room temperature for 1 h. Solvents were evaporated under vacuo and the residue was purified by SPE-SCX cartridge (10 g) eluting with methanol and 2N ammonia in methanol. Ammonia fractions were evaporated in vacuo to afford the title compound (D56) (110 mg)
