Acetic Anhydride → 2-{2-[Acetyl(phenyl)amino]ethenyl}-3-methyl-1,3-benzoxazol-3-ium iodide

Participants

Reaction Steps

A mixture of 27.7 g (0.1 mole) of 2,3-dimethylbenzoxazolium iodide, 21.6 g (0.11 mole) of N,N'-diphenylformamidine, and 100 ml of acetic anhydride was made and was then refluxed. After cooling the mixture refluxed, 300 ml of acetone were added and were then filtrated to take crystals. The resulted crystals were washed with acetone, so that the objective matter was obtained. The yield thereof was 26.0 g (62%).
