Abstract

Indazolone - 5 - octadecenylsuccinamic acid is prepared by heating together 5-aminoindazolone hydrochloride, octadecenyl-succinic acid anhydride, and pyridine. 5 - Pyrazolone - 3 - octadecenylsuccinamic acid and 2 - (1 - hydroxy - 2 - naphthoylamino) - 1 : 3 : 4 - triazole - 5 - octadecenylsuccinamic acid are similarly prepared. 2 : 5 - Di - (1 - hydroxy - 2 - naphthoylamino) - 1 : 3 : 4 - triazole is prepared by heating together 1-hydroxy-2-naphthoic acid, guanazol, and chlorobenzene, adding phosphorus trichloride, and continuing heating. 2 - (1 - hydroxy - 2 - naphthoylamino) - 5 - amino - 1 : 3 : 4 - triazole is prepared by heating together phenyl 1-hydroxy-2-naphthoate and guanazol. Specifications 465,823, [Group XX], 590,637, 615,218, [Group XX], 619,507, 638,039 and 663,190 are referred to.
