Procedure

The title compound was prepared in accordance with the general method of Example 191(C), from 3,5-difluoro-N1-methylbenzene-1,2-diamine (1.50 g, 9.50 mmol) and 2-chloroacetic acid (1.3 g, 14 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column, Cyclohexane/AcOEt:70/30 as eluent) to afford 443 mg of 2-(chloromethyl)-4,6-difluoro-1-methyl-1H-benzo[d]imidazole (Yield: 22%) as a purple solid.
