Preparation method of 2-aminobenzoxazole compound

The present invention relates to a method for preparing a 2-aminobenzoxazole compound. Comprising the following steps: (1) condensation reaction: taking o-aminophenol and nitrobenzoyl chloride compounds as raw materials, synthesizing amide intermediates in an alkaline solution system. The highly selective double-base combination system does not react with the raw material and can neutralize the acid gas generated by the reaction; (2) Cyclization reaction: acid is added to the condensation reaction solution as a catalyst, and 2-nitrobenzoxazole compounds are generated after dehydration. The solid super acid catalyst used is efficient and easy to separate and recycle; (3) hydrogenation hydrogenation reaction: 2-nitrobenzoxazole compounds are catalyzed to obtain 2-aminobenzoxazole compounds. The bi-alkali system and solid super acids used in the present invention are highly selective, product quality and yield are high. The operation is safe and simple, the raw material cost is low, in line with the green and environmentally friendly production concept, which is conducive to industrial production.
