실험 절차

A solution of 1,1-dimethylethyl 2-{4-[(methylamino)carbonyl]phenyl}-4,5,7,8-tetrahydropyrazolo[3,4-d]azepine-6(2H)-carboxylate (184 mg, 0.50 mmol; may be prepared as described in Description 24) in dichloromethane (2 ml) was treated with trifluoroacetic acid (2 ml). The mixture was stirred at room temperature for 2 hours. The mixture was diluted with methanol and passed down a SCX cartridge eluting with methanol and then a 2M solution of ammonia in methanol. The basic fractions were combined and evaporated to afford the title compound (D25); MS (ES+) m/e 271 [M+H]+.
