Allyl bromide → HCID 57890016, compound

Participants

Reaction Steps

Sodium hydride (60% in oil, 0.025 g, 1.04 mmol) was added in one portion to a solution of 3-(2,4-dimethoxyphenyl)-7-(trifluoromethyl)-1H-indazole (0.150 g, 0.49 mmol) in DMF. After the gas evolution ceased, allyl bromide (0.07 mL, 0.7 mmol) was added and the reaction mixture was stirred at ambient temperature to 50° C. overnight. The cool reaction mixture was partitioned with EtOAc and 1 N HCl. The organic phase was washed with brine and dried (Na2SO4). The resulting residue was purified by flash chromatography or by HPLC chromatography through silica gel columns, 150×12 mm (Biotage, Charlottesville, Va.), at 10 mL/min with methyl-t-butyl ether/hexane (gradient elution, 1:9 to 1:1) to give the title compound (0.062 g) as a white solid.
