Versuchsvorschrift

A solution of N,N-dimethyl-4-(5,6,7,8-tetrahydropyrazolo[3,4-d]azepin-2(4H)-yl)benzamide (24.0 mg, 0.085 mmol) (may be prepared as described in Description 42) in dichloromethane (2 ml) was treated with 2-methylpropanal (16.0 μl, 0.17 mmol) and acetic acid (1 drop) and stirred at room temperature. Sodium triacetoxyborohydride (36.0 mg, 0.17 mmol) was added and the mixture was stirred at room temperature for approximately 50 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 (E1); MS (ES+) m/e 357 [M+NH3]+.
