Abstract

1308917 Indazoles; hydrazine derivative IMPERIAL CHEMICAL INDUSTRIES Ltd 4 Jan 1971 [26 Jan 1970] 3585/70 Heading C2C [Also in Division C4] 2 - Methyl - 3 - amino - 5,7 - dinitro - indazole is prepared by condensing hydrazine hydrate with 2-methoxy-3,5-dinitro-benzonitrile to yield 2 - cyano - 4,6 - dinitro - phenylhydrazine which is boiled with aq. HCl and sodium acetate to give 3-amino-5,7-dinitro-indazole which is treated with dimethyl sulphate in nitrobenzene. The following compounds are prepared using one or more of the preceding synthesis steps: 2-methyl- 5 - amino - indazole, 2 - methyl - 3 - amino - 5- nitro - 7 - (chloro - or bromo - ) - indazoles and 2- (ethyl or n-butyl)-3-amino-5,7-dinitroindazoles.
