YieldReaction ConditionsOperation in experiment
67% In isopropyl alcohol; for 60h;Heating / reflux; EXAMPLE 21 4-Ethoxy-3-fluoroanilino-N-(2,4-dichloro-5-methoxyphenyl)-2-cyano-2-propenamide To a suspension of <strong>[846023-24-3]2-cyano-N-(2,4-dichloro-5-methoxyphenyl)acetamide</strong> (5.9 g, 22.7 mmol) in 400 mL of isopropanol was added 4-ethoxy-3-fluoroaniline (3.7 g, 23.8 mmol). This mixture was heated to reflux to give a clear solution. To this solution, triethylorthoformate (11.6 mL, 69.6 mmol) was added dropwise and the reaction mixture was heated at reflux for 18 hours. Additional triethylorthoformate (11.6 mL, 69.6 mmol) was added dropwise and the reaction mixture was heated at reflux for 42 hours. The mixture was allowed to cool to room temperature and the solid was collected by filtration, washed with ethyl acetate, and dried in vacuo at 40 C. to give 6.4 g (67%) of 4-ethoxy-3-fluoroanilino-N-(2,4-dichloro-5-methoxyphenyl)-2-cyano-2-propenamide as a grey solid, mp 245-247 C.; MS 424.1, 426.1 (M+H)+ Analysis for C19H16Cl2FN3O3; Calcd: C, 53.79; H, 3.80; N, 9.90. Found: C, 53.39; H, 3.97; N, 9.69.
