See p-Tolylsulfonyl hydrazine 4-Toluenesulfonic acid sodium salt p-Toluenesulfonic acid, sodium saK. See Sodium toluenesulfonate... [Pg.2505]

Synonyms Benzenesulfonic acid, 4-methyl-, hydrazide Hydrazine, p-tolylsulfonyl- p-Toluenesulfonhydrazide p-Toluenesulfonic acid, hydrazide p-Toluenesulfono-hydrazide p-Toluenesulfonyl hydrazide N-Toluolsulfonyl hydrazine Tolylsulfonyl hydrazine Tosyl hydrazide... [Pg.2505]

The third approach was based on cyclodehydratation of 6-aroylhydrazido-purine derivative 278 under catalysis by p-toluenesulfonic acid giving rise to tricyclic 279. The necessary intermediate 278 was accessible easily by transformation of the 6-methylthio derivative 277 by, e.g., isonicotinoyl hydrazide. Compounds 279 are stable in acid in contrast to parent triazolopurines 274 (X = H). Notable is their bronchodilatation effect, up to 100 x greater than that of theophylline (92TL3151) (Scheme 80). [Pg.128]
