Procedure

To a solution of 2-[(3R)-12-[[4-(4-benzylpiperazin-1-yl)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(12),2(6),8,10-tetraen-3-yl]acetonitrile (270 mg, 0.55 mmol, 1.00 equiv) in methanol (25 mL) were added LiOH.H2O (70 mg) and H2O2 (30%) (1.2 mL). The resulting solution was stirred for 4 h at 0° C. in a water/ice bath. The reaction was then quenched by the addition of 100 mL of Na2SO3 (sat.). The resulting solution was extracted with 6×50 mL of dichloromethane and the organic layers combined. After evaporation, the residue was purified by silica gel column with dichloromethane/methanol (4:1). This resulted in 90 mg (32%) of Compound I-122 as a white solid.
