Abstract

This invention provides new compounds of formula I, I wherein R1 is alkyl of 1 to 10 carbon atoms, cyclo alkyl of 3 to 8 carbon atoms or phenyl, R2 is hydrogen, nitro, lower alkyl, methylR3 is halogen, nitro, lower alkyl, methyl thio, hydroxy, lower alkoxy, acyloxy or acylamino, with the proviso that when R3 is in the 5 position, and R1 and R3 are identical and signify a straight alkyl chain of 1 to 5 carbon atoms, R2 is lower alkyl, useful as anti-phlogistics.
