To a solution of 3 g of 2-hydroxymethylbenzimidazole in 20 mL of dried DMF at 0° was added portionwise 1 g of NaH (50% oil dispersion). After stirring at room temperature for 15 minutes, 4.3 g of p-nitrobenzyl bromide was added. The reaction mixture was stirred for 16 hours and then diluted with ethyl acetate and washed with water. The organic layers were dried and evaporated. Recrystallization from acetonitrile afforded 3.5 g of a brownish solid; m.p. 162.5-165°.
