反应详情

(6-Nitro-1H-benzoimidazol-2-yl)-methanol (1.00 g, 5.18 mmol) was dissolved in methanol (50.0 mL) and 3.00 M hydrogen chloride in methanol (8.63 mL, 25.9 mmol). 10% Palladium on Carbon (50% wet) (55.1 mg, 0.0259 mmol) was added and the reaction was hydrogenated at 40 psi. for 3 hours. The reaction was then filtered through celite to remove the catalyst and then concentrated under reduced pressure to obtain (6-Amino-1H-benzoimidazol-2-yl)-methanol; dihydrochloride as a brown foam (1.13 g, 92%). Product is used without further purification.
