実験手順
To a solution of 4-(5,6,7,8-tetrahydropyrazolo[3,4-d]azepin-2(4H)-yl)benzamide (may be prepared as described in Description 37) (31 mg, 0.12 mmol) in dichloromethane (3 ml) was added acetone (14 mg, 0.24 mmol) and acetic acid (2 drops). The resulting mixture was stirred at room temperature, under argon, for 20 minutes. Sodium triacetoxyborohydride (51 mg, 0.24 mmol) was added and stirring continued for 2 hours. A further 6 eq. of acetone was added and stirring continued over the weekend. Methanol was added and the crude mixture was purified by SCX, eluting with methanol and then with 2M ammonia/methanol. The basic fractions were combined and solvent evaporated in vacuo. The crude product was triturated with ether and filtered to afford the title compound (E17). MS (ES+) m/e 299 [M+H]+.
