Versuchsvorschrift
Formaldehyde (37% in water, 1 mL, 13.3 mmol) was added to a solution of 1H-benzo[d]imidazole (1.57 g, 13.3 mmol) in THF (60 ml). After 10 minutes, the solvent was removed and dried to give 1H-benzo[d]imidazol-1-ylmethanol as a brown solid which was used without any further purification. 1H NMR (DMSO-d6) δ 5.60 (d, J=7.09 Hz, 2H), 6.70 (m, 1H), 7.25 (m, 2H), 7.65 (d, J=9.13 Hz, 2H), 8.26 (s, 1H).
