Tosylmethyl isocyanide → 1H-Imidazole, 1,5-diphenyl-

Participants

Reaction Steps

To a stirred solution of (E)-N-benzylideneaniline (1.0 mmol) in THF (5 mL) was added TOSMIC (1.1 mmol) and t-BuONa (2.2 mmol). The solution was allowed to stir at room temperature for 5 days. The solvent was evaporated under reduced pressure and the crude product was absorbed on silica gel. After purification by flash column chromatography on silica gel the desired product was obtained in 18% yield. 1H NMR: 7.10-7.16 (m, 2H), 7.16-7.23 (m, 2H), 7.23-7.31 (m, 4H), 7.36-7.42 (m, 3H), 7.73 (s, 1H)
