실험 절차
Sodium hydride (60% dispersion in mineral oil, 0.9 g, 22.5 mmol, 4.60 equiv) was treated with tert-butyl N-(4-hydroxycyclohexyl)-N-methylcarbamate (1.8 g, 7.85 mmol, 1.6 equiv) in distilled THF (50 mL) at 0° C. for 1 h under nitrogen. Then a solution of 25.1 (1.8 g, 4.88 mmol, 1.00 equiv) in 15 mL of THF was added to the reaction mixture and the latter was stirred for 2 h at 60° C. The reaction was then quenched by the addition of 20 mL of water at 0° C. and extracted with ethyl acetate (3×100 mL). The combined organic layers were washed with brine and dried over anhydrous sodium sulfate. After filtration and concentration under reduced pressure, the residue was loaded onto a silica gel column with ethyl acetate/petroleum ether (1:5) and purified to afford tert-butyl N-(4-[[(3R)-3-[2-[(tert-butyldimethylsilyl)oxy]ethyl]-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 (34.1, 1.6 g, 58%) as a yellow oil.
