Participants

Reaction Steps

To a stirred solution of (2,4-dichlorophenyl)[7-(diethylamino)-1-(3-hydroxypropyl)-1H-benzimidazol-2-yl]methanone (300 mg, 0.714 mmol) in tetrahydrofuran (7 mL) was added a solution of methyl magnesium bromide in diethyl ether (3.0 M, 714 μL, 2.14 mmol) at 0° C. After being stirred for 6.5 h at room temperature, the reaction mixture was quenched with aqueous ammonium chloride at 0° C., diluted with ethyl acetate, washed with water and brine, dried over sodium sulfate, filtrated, and concentrated in vacuo. The resulting solid was washed with diethyl ether to afford the desired product as a yellow solid (210 mg, 0.481 mmol, 67%).
