Reaction Steps

To a mixture of {trans-4-[(6-nitrothieno[3,2-b]pyridin-7-yl)amino]cyclohexyl}methanesulfonic acid (34 mg, 0.092 mmol) in methylene chloride (0.30 mL) was added 1 drop of DMF and thionyl chloride (33 μL, 0.46 mmol). The resulting mixture was stirred at 42° C. for 1 h, then the solvents were evaporated to give the crude {trans-4-[(6-Nitrothieno[3,2-b]pyridin-7-yl)amino]cyclohexyl}methanesulfonyl chloride. To the crude sulfonyl chloride made above was added 2.0 M methylamine in THF (0.30 mL, 0.60 mmol). The mixture was stirred at room temperature for 30 h. LCMS showed a small amount of starting material remaining More 2.0 M methylamine in THF (0.15 mL) was added and stirred for 30 min, to give a complete reaction. The solvents were evaporated and the resultant residue was dried in vacuo to give the crude product which was used in the next step without further purification. LCMS calculated for C15H21N4O4S2 (M+H)+: m/z=385.1. Found: 385.1.
