Procedure

To a solution of 5-cyclopropyl-1-(2-(4-fluorophenyl)-2-oxoethyl)-8-methoxy-2,3,5,6-tetrahydrobenzo[b][1,5]diazocin-4(1H)-one (65.0 mg, 0.170 mmol) from Example 5 in ethanol (1 ml) was added sodium borohydride (6.4 mg, 0.170 mmol) and the reaction mixture was stirred at room temperature over weekend. Then was added acetone (0.062 ml) followed by dilution with dichloromethane. The resulting solution was washed with water and the organic phase was dried over sodium sulfate and filtered. Evaporation gave the desired product (30 mg, 46%).
