Acetaldehyde → HCID 86669135, compound

Participants

Reaction Steps

To a suspension of benzotriazole (139 g, 1.16 mol) in toluene (2 L) in a 3 L, four neck flask under nitrogen atmosphere was added at room temperature a solution of 4-bromoaniline (200 g, 1.16 mol) in toluene (300 mL). Then, via an addition funnel was added drop wise acetaldehyde (64.7 ml, 1.17 mol) in solution in toluene (200 mL). The reaction mixture becomes progressively homogenous and then gives a precipitate. The resulting mixture is stirred for 12 hours under nitrogen atmosphere and then filtered. The precipitate is recrystallised in toluene to afford the title compound as a white solid (304 g, 82%).
