Versuchsvorschrift

A solution of tert-butyl N-(4-hydroxycyclohexyl)carbamate (194 mg, 0.90 mmol, 1.40 equiv) in anhydrous tetrahydrofuran (5 mL) was added sodium hydride (60% dispersion in mineral oil, 77 mg, 1.92 mmol, 3.00 equiv) at 0° C. under nitrogen. After stirred at room temperature for 1 h, 12-chloro-7-thia-9,11-diazatricyclo[6.4.0.0^[2,6]]dodeca-1(8),2(6),9,11-tetraene (200 mg, 0.95 mmol, 1.00 equiv) was added and the resulting solution was stirred overnight at ambient temperature for additional 5 h. The reaction was then quenched with water and extracted with 3×30 mL of 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 ethyl acetate/petroleum ether (1:5) to give the resulted tert-butyl N-(4-[7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yloxy]cyclohexyl)carbamate (308 mg, 83%) as a yellow solid. MS (ES, m/z): 390 (M+H+).
