Reaction Steps

A 50-mL round-bottom flask placed a solution of 10,12-dichloro-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraene (500 mg, 2.04 mmol, 1.00 equiv) in anhydrous CH3CN (20 mL) was added trans-cyclohexane-1,4-diamine (280 mg, 2.45 mmol, 1.20 equiv) and potassium carbonate (844 mg, 6.11 mmol, 3.00 equiv) at room temperature. The resulting solution was stirred overnight at 80° C. under nitrogen. The resulting solution was diluted with EtOAc, washed with brine, dried over anhydrous sodium sulfate and concentrated under vacuum. This resulted (520 mg, crude) of 1-N-[10-chloro-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]cyclohexane-1,4-diamine as a white solid which was used directly for next step without further purification.
