Procedure

Sodium hydride (60% dispersion in mineral oil, 240 mg, 6.00 mmol, 3.00 equiv) was treated with tert-butyl N-(4-hydroxycyclohexyl)-N-methylcarbamate (642 mg, 2.80 mmol, 1.40 equiv) in freshly distilled tetrahydrofuran (14 mL) at 0° C. under nitrogen for 30 min. To this mixture was added a solution of (3S)-3-[[(tert-butyldimethylsilyl)oxy]methyl]-12-chloro-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraene (710 mg, 2.00 mmol, 1.00 equiv) in 5 mL of THF via syringe and the resulting solution was stirred overnight at room temperature. After completion, the reaction was quenched with saturated aqueous NH4Cl and extracted with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. The residue was applied onto a silica gel column with dichloromethane/methanol (8:1) to give the desired tert-butyl N-(4-[[(3S)-3-[[(tert-butyldimethylsilyl)oxy]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 (963 mg, 88%) as light yellow oil. MS: m/z 548 (M+H)+.
