Reaction Steps

A solution of 3-[4-(5,6,7,8-tetrahydropyrazolo[3,4-d]azepin-2(4H)-yl)phenyl]-1,3-oxazolidin-2-one (25.0 mg, 0.08 mmol) (may be prepared as described in Description 27) in dichloromethane (3 ml) was treated with acetone (25.0 μl, 0.34 mmol) and acetic acid (1 drop) and stirred at room temperature. Sodium triacetoxyborohydride (72.0 mg, 0.34 mmol) was added and the mixture stirred for 3 hours and then overnight. 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 (E9); MS (ES+) m/e 341 [M+H]+.
