Procedure

To a solution of 1,1-dimethylethyl 2-[4-(aminocarbonyl)phenyl]-4,5,7,8-tetrahydropyrazolo[3,4-d]azepine-6(2H)-carboxylate (may be prepared as described in Description 36) (167 mg, 0.47 mmol) in dichloromethane (14 ml) was added trifluoroacetic acid (7 ml). The resulting mixture was stirred at room temperature, under argon, for 2 hours and then diluted with methanol. Reaction was purified by SCX, eluting with methanol and then 2M ammonia/methanol. The basic fractions were combined and solvent evaporated in vacuo to afford the title compound (D37). MS (ES+) m/e 257 [M+H]+.
