Reaction Steps

To a solution of 2-[(tert-butyldimethylsilyl)oxy]-3-[(3R)-12-chloro-7-thia-9,11-diazatricyclo[6.4.0.0^[2,6]]dodeca-1(12),2(6),8,10-tetraen-3-yl]propanenitrile (150 mg, 0.38 mmol, 1.00 equiv) in NMP (1 mL) was added triethylamine (310 mg, 3.06 mmol, 8.00 equiv) and 4-(morpholin-4-yl)cyclohexan-1-amine (560 mg, 3.04 mmol, 8.00 equiv) at room temperature. The resulting solution was stirred overnight at 75° C. under nitrogen. After cooling to room temperature, the resulting solution was 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 185 mg (90%) 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 as a white solid. MS: m/z 542 (M+H)+.
