Abstract

Pyrazolo 3, 4 - b quinoxalines of formula (where R1 = H or alkylf R2 is opt. substd. phenyl, R3 & R4 = alkyl, sulphoalkyl, hydroxyalkyl or alkylsulphonylaminoalkyl; R5 = H, halogen, alkyl or alkoxy) are prepd. by reaction of the corresp. 5-sulphonyliminopyrazolone derivs. with the corresp. derivs of p-phenylene-diamine acid addn. salts in the presence of an oxidn. agent forming a sulphinic acid by prod.
