Procedure

To a solution of 1,1-dimethylethyl 2-[4-(1-piperidinyl)phenyl]-4,5,7,8-tetrahydropyrazolo[3,4-d]azepine-6(2H)-carboxylate (may be prepared as described in Description 33) (70 mg, 0.18 mmol) in dioxan (1 ml) was added 4M hydrochloric acid in dioxan (2 ml). The resulting mixture was stirred at room temperature, under argon, overnight. The reaction mixture was diluted with methanol and then 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 (D43). MS (ES+) m/e 297 [M+H]+.
