METHODS FOR PREPARING BREXPIPRAZOLE, KEY INTERMEDIATES THEREOF AND SALTS THEREOF

摘要

The present invention relates to the methods for preparing brexpiprazole, the analogs, key intermediates, and salts thereof, specifically, the present invention relates to a new method for preparing brexpiprazole, the analogs, key intermediates, and salts thereof, and the key intermediates, and salts thereof provided during the preparation. The preparation method has a mild reaction condition, stable intermediate, easy operation, and uses cheap and easy-to-get reagents, thus it saves the synthesis cost, shortens the production cycle, improves the yield and product quality, and is suitable for mass production.
