Reaction Steps

To a solution of 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)-N-methylcarbamate (100 mg, 0.2 mmol, 1.00 equiv) in 10 mL of methanol was added LiOH.H2O (30 mg, 0.7 mmol, 3.26 equiv) and H2O2 (30%, 0.8 mL) and stirred for 4 h at 0° C. The reaction was then quenched with saturated aqueous NaHSO3, extracted with 3×50 mL of ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and concentrated under vacuum. The residue was purified by column chromatography on silica gel with EtOAc/PE (1:2) to give the desired 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)-N-methylcarbamate (85 mg) as a light yellow oil.
