Procedure
Trans-3-Ethoxypropenoyl chloride (0.74 g) was added at 0° to a stirred solution of 4-bromo-2-methylaniline (0.93 g) in pyridine (10 cm3). After 0.5 hours water (40 cm3) was added, the solid material was filtered off, washed with water (30 cm3) and dried. The product was recrystallised from ethyl acetate to afford trans-N-(4-bromo-2-methylphenyl)-3-ethoxypropenamide, m.p. 163°-164°, (1.3 g).
