Reaction Steps

To a solution of 2-[(3R)-12-[[4-(methylamino)cyclohexyl]oxy]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-3-yl]ethan-1-ol (120 mg, 0.35 mmol, 1.00 equiv) in distilled DMF (5 mL) was added 2-chloro-1-(pyrrolidin-1-yl)ethan-1-one (75 mg, 0.51 mmol, 1.50 equiv) and potassium carbonate (26 mg, 0.19 mmol, 2.00 equiv) at room temperature. The resulting solution was stirred overnight at room temperature. The reaction mixture was diluted with DCM (100 mL), washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with methanol/DCM (1:10) to afford the desired 2-[(4-[[(3R)-3-(2-hydroxyethyl)-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)(methyl)amino]-1-(pyrrolidin-1-yl)ethan-1-one (130 mg, 82%) as a white solid.
