Reaction Steps

A mixture of 4-iodobenzylalcohol (1.23 g, 5.25 mmol), 3-(trifluoromethyl)-4,5,6,7-tetrahydro-1H-indazole (950 mg, 5 mmol), copper (I) iodide (10 mol %, 95 mg, 0.5 mmol), N,N-dimethylglycine (20 mol %, 103 mg, 1 mmol) and potassium carbonate (1.45 g, 10.5 mmol) in dimethylsulfoxide (30 ml) was stirred at 130° C. in an oil bath for 23 h. The reaction mix was cooled and partitioned between dichloromethane (30 ml) and brine (150 ml). The organic layer was removed filtered and the solvent removed under reduced pressure. The resulting product was purified by flash column chromatography on a Biotage 40+M column eluting from 0-60% ethyl acetate in pentane to give the title compound as a yellow oil (1.27 g, 86%).
