PROCEDURE

实验过程

3.4 g (0.0125 Mol) of 2-(phenylsulfonyl)-ethanimidic acid ethyl ester was stirred together with 2.2 g (0.015 mol) benzofuran-2-carboxylic acid hydrazide in 80 ml chloroform for 24 hours at 50° C. The resulting precipitate was filtered off and dried. 2.67 g of benzofuran-2-carboxylic acid (1-amino-2-benzenesulfonyl-ethylidene)-hydrazide was obtained as off-white crystals. Mp.: 205-220° C.
