Participants

Reaction Steps

A suspension of 1,1-dimethylethyl 5-amino-1H-benzimidazole-2-carboxylate (0.147 g, 0.630 mmol) in dichloromethane (5 mL) was cooled in an ice bath. Pyridine (0.076 mL, 0.945 mmol) and acetic anhydride (0.059 mL, 0.630 mmol) were added. The reaction mixture was filtered and the collected solid was washed with dichloromethane and dried under vacuum to give the title compound (0.160 g, 92%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ ppm 13.06 (s, 1H), 10.05 (s, 1H), 8.14 (s, 1H), 7.61 (m, 1H), 7.24 (m, 1H), 2.04 (s, 3H), 1.55 (s, 9H). MS: m/z 276 (M+1).
