Abstract

A 4-thioazolidine carboxylic acid compound of the formula I is reacted an arylamine of the formula II, the substituents R<1>, R<2>, R<3>, R<4> and A each being as defined in Claim 1. The process is easy to carry out and economical, and the products are obtained in high purity and yield. Compared with known processes, the end products are easier to prepare and more rapidly freed of by-product. <IMAGE>
