ABSTRACT:
A process for preparing 2-methylbenzoxazole by cyclizing acetamidophenol with the simultaneous elimination of the water of reaction. The process involves the drying and melting of the acetamidophenol, the cyclization of acetamidophenol to 2-methylbenzoxazole, and the removal of the water of reaction and the 2-methylbenzoxazole from the reaction mixture after the cyclization step by distillation. All the steps are carried out in a dryer.
