HCID 74903Acetamide, N-(3,5-dimethylphenyl)-Yield 93.9%

Conditions

Temperature: 100 °C

Procedure

A mixture of the 3,5-dimethylaniline (12.1 g, 100.0 mmol) and acetic anhydride (12.1 g, 118.6 mmol) was stirred at 100° C. for 1 h. The crude product was then recrystallized from methanol to provide N-(3,5-dimethylphenyl)acetamide (15.3 g, 93.9%) as a white flake; m.p. 140-142° C. (Lit. 139.6-140.2° C.5.
