Participants

Reaction Steps

The title compound was prepared in accordance with the general method of Example 191(C), from N1-isopropylbenzene-1,2-diamine (3.88 g, 25.82 mmol) and 2-chloroacetic acid (3.70 g, 39 mmol). The crude residue was purified over silicagel chromatography (prepacked 85 g silicagel column, Cyclohexane/AcOEt: 70/30 as eluent) to afford 2.05 g of 2-(chloromethyl)-1-isopropyl-1H-benzo[d]imidazole (Yield: 38%) as a light brown oil.
