Reaction Steps

The mixture of 1-methyl-1H-benzo[d]imidazol-6-ol (600 mg, 4.03 mmol), BrCH2COOEt (372 mg, 4.03 mmol) and K2CO3 (1.1 g, 8.06 mmol) in DMF (8 mL) was stirred at room temperature for 16 h. DCM (100 mL) and water (100 mL) was then added to the reaction and the organic layer washed with water (50 mL), brine (50 mL) and dried over Na2SO4 before filtering and concentration to give the crude desired product (560 mg, Yield 60%). LCMS (m/z): 235.1 (M+1).
