Reaction Steps

A 50-mL round-bottom flask purged and maintained with an inert atmosphere of nitrogen was charged with tert-butyl N-(4-[[(3R)-3-(cyanomethyl)-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]-1-methylcyclohexyl)carbamate (600 mg, 1.36 mmol, 1.00 equiv) in methanol (8.0 mL). Then LiOH.H2O (171 mg, 4.08 mmol, 3.00 equiv) and H2O2 (30%, 1.0 mL) were added at 0° C. and the resulting solution was stirred overnight at this temperature. The reaction was then quenched by the addition of 40 mL of NaHSO3 (aq.) and extracted with 3×60 mL of ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1/1) to afford tert-butyl N-(4-[[(3R)-3-(carbamoylmethyl)-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]-1-methylcyclohexyl)carbamate (450 mg, 72%) as a white solid.
