Reaction Steps

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 (264 mg, 1.08 mmol, 1.00 equiv) in DMF (15 mL) was added 1-N,1-N-dimethylcyclohexane-1,4-diamine hydrochloride (270 mg, 1.51 mmol, 1.40 equiv) and potassium carbonate (450 mg, 3.26 mmol, 3.00 equiv) was stirred overnight at 80° C. in an oil bath under nitrogen. The resulting solution was diluted with of EtOAc and washed with of brine. The organic layer was dried over anhydrous sodium sulfate and concentrated under vacuum to provide the resulted 4-N-[10-chloro-7-thia-9,11-diazatricyclo[6.4.0.0[2,6]]dodeca-1(8),2(6),9,11-tetraen-12-yl]-1-N,1-N-dimethylcyclohexane-1,4-diamine (300 mg, 79%) as a yellow solid. LC-MS: (ES, m/z) 252 (M+H+).
