Reaction Steps

To a solution of 1H-indazole-3-carbonitrile (11 mg, 0.077 mmol) in DMF (500 μL) was added potassium carbonate and the whole was stirred at RT for 30 min before 2-(2-bromoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (24 mg, 0.077 mmol) was added. The reaction mixture was heated to 60° C. and this temperature was maintained for 1.5 h before the reaction mixture was cooled to RT, then diluted with water (5 mL). The organics were extracted with diethyl ether (10 mL), EtOAc (10 mL) and DCM (10 mL), then combined and the suspension concentrated to dryness. The residue was dissolved in DMSO (1 mL) and purified by preparative reverse phase HPLC to give the title compound as a white solid (4 mg, 0.01 mmol, 14%).
