Ammonia → 3-Ethenylbenzamide

Participants

Reaction Steps

3-Vinylbenzoyl chloride is saturated with ammonia gas to afford an immediate precipitate. This mixture is poured into EtOAc and extracted with water and brine. The EtOAc is dried, filtered, and concentrated to afford the title compound: mp=128-130° C.; 1H NMR (CDCl3) δ 7.86 (d, J=1.3 Hz, 1H), 7.66 (dd, J=8.6, 1.0 Hz, 1H), 7.57 (d, 7.8 Hz, 1H), 7.41 (t, 7.8 Hz, 1H), 6.75 (dd, J=17.4, 10.9 Hz, 1H), 6.05 (br s, 1H), 5.83 (d, J=17.9 Hz, 1H), 5.61 (br s, 1H), 5.34 (d, J=10.9 Hz, 1H).
