Procedure

Terephthaloyl chloride (203 g, i mol) is added in the course of 30 minutes to a solution of ω-laurolactam (403 g, 2 mol) in 1600 ml of cyclohexane and 475 ml of pyridine at room temperature. The mixture is then refluxed for 3 h. After cooling, the flask contents are poured into 3 1 of ice water and the resulting light yellow precipitate is filtered off by suction and dried. Yield 498 g (95%).
