YieldReaction ConditionsOperation in experiment
26% In isopropyl alcohol;Heating / reflux; EXAMPLE 22 2-Cyano-N-(2,4-dichloro-5-methoxyphenyl)-3-(thien-3-ylamino)prop-2-enamide To a suspension of <strong>[846023-24-3]2-cyano-N-(2,4-dichloro-5-methoxyphenyl)acetamide</strong> (1.57 g, 6.06 mmol) in 200 mL of iso-propanol was added 3-aminothiophene (600 mg, 6.06 mmol). This mixture was heated to reflux and triethylorthoformate (6.5 mL, 39.1 mmol) was added dropwise. The reaction mixture was heated at reflux overnight. Additional 3-aminothiophene (214 mg, 2.16 mmol) was added and the reaction mixture was heated at reflux for 5 hours. Additional 3-aminothiophene (100 mg, 1.01 mmol) was added and the reaction mixture was heated at reflux for 2.5 hours. The mixture was allowed to cool to room temperature and the solid was collected by filtration, washed with iso-propanol to give 572 mg (26%) of 2-cyano-N-(2,4-dichloro-5-methoxyphenyl)-3-(thien-3-ylamino)prop-2-enamide as a tan solid, mp >250 C.; MS 366.0, 368.2 (M-H)- Analysis for C15H11Cl2N3O2S-1.0 H2O; Calcd: C, 46.64; H, 3.39; N, 10.88. Found: C, 46.37; H, 2.94; N, 10.60.
