To a solution of 2-[(tert-butyldimethylsilyl)oxy]-3-[(3R)-12-[[4-(morpholin-4-yl)cyclohexyl]amino]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(12),2(6),8,10-tetraen-3-yl]propanenitrile (180 mg, 0.33 mmol, 1.00 equiv) in methanol (5 mL) was added LiOH.H2O (40 mg, 0.95 mmol, 3.00 equiv) and 0.5 mL of H2O2 (30%) at 0° C. The resulting solution was stirred for 1 h at 0° C. and then quenched with saturated aqueous Na2SO3, diluted with DCM (30 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (20:1) to give 130 mg (70%) of 2-[(tert-butyldimethylsilyl)oxy]-3-[(3R)-12-[[4-(morpholin-4-yl)cyclohexyl]amino]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(12),2(6),8,10-tetraen-3-yl]propanamide as a white solid. MS: m/z 560 (M+H)+.
