Abstract

Cpds of formula (I): (where (a) R1=3-pyridyl and R2=benzoyl, methyl, formyl, N'-methyl-hydrazino-methyl,-N'-carbomethoxy - hydrazino-methyl, carboxyl, or (di)methylcarbamoyl; (b) R1=3-pyridyl-N-oxide and R2=carbamoyl, methyl or formyl; (c) R1=2-pyridyl and R2= carbamoyl, or (di)-methylcarbamoyl; (d) R1=2-pyridyl-N-oxide and R2= (di) chloromethyl or methyl; (e) R1=4-pyridyl and R2=chloro methyl, or (di)methylcarbamoyl;(f) R1=4-pyrimidyl, 2-pyrazinyl, 4-pyrimidyl-mono-N-oxide or 2-pyrazinylmono-N-oxide and R2=carbamoyl; (g) R1=4-pyridyl-N-oxide and R2=methyl; (h) R1=4-pyrazinyl and R2=carbethoxy) are prepd by reacting a benzofuroxan with a cpd (II): or its tautomer, where one of R4 and R5=R1 and the other R2; R6= a residue which can be split off, pref. leaving a carbonium ion. Pref. reactions use a vinyl cpd with an opt. substd amino gp as a residue to be split off.
