Reaction Steps

A solution of tert-butyl N-(4-[[(3S)-3-([2-[(4-methoxyphenyl)methoxy]ethoxy]methyl)-7-thia-9,11-diazatricyclo[6.4.0.0^[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)-N-methylcarbamate (700 mg, 1.17 mmol, 1.00 equiv) in dichloromethane (10 mL)/water (0.5 mL) was added DDQ (399 mg, 1.76 mmol, 1.50 equiv) and the resulting solution was stirred for 14 hrs at 25° C. under nitrogen. The resulting solution was diluted with water and extracted with 3×100 mL of ethyl acetate. The organic layers were combined, washed with brine, dried over sodium sulfate and concentrated in vacuo. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:1) to give tert-butyl N-(4-[[(3S)-3-[(3-hydroxypropoxy)methyl]-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]oxy]cyclohexyl)-N-methylcarbamate (370 mg, 64%) as a colorless oil. MS: m/z 478 (M+H)+.
