反应详情

Thiobenzamide (13.7 g, 0.10 mole) and desyl chloride (23.1 g, 0.10 mole) are heated under reflux in isopropyl alcohol (100 ml) for three hours. When the reaction mixture is cooled, the white solid precipitate formed is filtered off, washed twice with isopropyl alcohol, and dried. The yield of triphenylthiazole, m.p. 84°-85.5° C., is 21.5 g or 69%.
