Reaction Steps

1H-benzo[d]imidazole-5-carboxylic acid (5.39 g, 33.3 mmol) was dissolved into anhydrous THF (100 ml) under argon. The solution was cooled in an ice bath and lithium aluminum hydride (70.0 ml of 1M solution in THF, 70.0 mmol) was added dropwise. The reaction mixture was allowed to warm to room temperature and stir overnight. The reaction mixture was cooled to 0° C. and ethyl acetate (90 ml) was carefully added, followed by methanol (15 ml) and water (15 ml). The mixture was stirred for 1 h and filtered through celite. The Solution was concentrated and dissolved in THF (200 ml) and washed with brine (2×100 ml), dried over Na2SO4, filtered and concentrated to yield the title compound ((1H-benzo[d]imidazol-5-yl)methanol) (1.26 g, 26%) as a yellow solid: 1H NMR (400 MHz, DMSO-d6) δ 8.15 (s, 1H), 7.54-7.47 (m, 2H), 7.13 (s, 1H), 5.14 (s, 1H), 4.58 (s, 2H).
