Procedure

To a solution of 2-(3-trifluoromethylpyrazol-4-yl)-ethanol (18 mg, 0.1 mmol) in DMF (0.5 mL) was added potassium carbonate (16 mg, 0.12 mmol). The reaction mixture was stirred at 60° C. for 25 min before 2-(2-bromoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (32 mg, 0.1 mmol) was added. Heating at 60° C. was maintained for 4 h before the reaction mixture was allowed to cool to RT. The whole was diluted with MeOH (0.5 mL), and filtered before being purified by preparative reverse phase HPLC to give the desired product as a white solid (17 mg, 0.04 mmol, 41%).
