| abstract | 1,153,561. Substituted para-phenylene diamines. GEVAERT-AGFA, N.V. 9 Jan., 1967 [18 Jan., 1966], No. 2241/66. Heading C2C. [Also in Divisions C4 and G2] Substituted p-phenylene diamines of the general formula wherein R<SP>1</SP> 1 is hydrogen, #-methylsulphonylaminoethyl or γ-sulphopropyl, R<SP>1</SP> 2 is hexadecyl, R<SP>1</SP> 3 is methyl, chloro or bromo, R<SP>1</SP> 4 is methyl, methoxy or bromo, R 5 is hydrogen or chloro and R 6 is hydrogen, and hydrochlorides thereof, are made by reducing with H 2 /Raney Ni or SnCl 2 the corresponding compounds in which the - NH 2 group is a 2: 6-dichlorophenylazo group; the compound of the above formula wherein R<SP>1</SP> 1 is hydrogen, R<SP>1</SP> 2 is n-decyl and R<SP>1</SP> 3 , R<SP>1</SP> 4 , R 5 and R 6 are each methyl is made by hydrolysis of 2 : 3 : 5 : 6 - tetramethyl - 4 - formylamino - N - n - decylaniline. The N - n - hexadecyl derivatives of 3 : 5 - dimethyl - aniline, 2 - chloro - 3: 5 - dimethylaniline, 3 - bromo - 5 - methoxyaniline, 3- chloro - 5 - methylaniline, 3 - bromo - 5 - methylaniline and 3: 5-dibromo-aniline are made by heating the amines with formic acid to obtain the corresponding N-formyl derivatives, refluxing the latter with n-hexadecyl bromide, evaporating and heating the residue with HCl to hydrolyse the N-formyl group. 3 - Bromo - 5 - methoxynitrobenzene and 3- chloro - 5 - methylnitrobenzene are made by diazotizing 3-bromo-4-amino-5-methoxynitrobenzene and 2 - amino - 3 - chloro - 5 - methylnitrobenzene and treating the diazonium compounds with hypophosphorous acid. 2 - Chloro - 3: 5 - dimethylnitrobenzene is made by diazotizing 2-amino-3: 5-dimethylnitrobenzene and treating the diazoninm compound with cuprous chloride and HCl. 3 - Bromo - 5 - methoxyaniline and 3 - chloro- 5-methylaniline are made by reducing 3-bromo- 5-methoxynitrobenzene and 3-chloro-5-methylnitrobenzene with stannous chloride. 3-Bromo- 4 - amino - 5 - methoxynitrobenzene is made by brominating 4-amino-5-methoxy-nitrobenzene. 3: 5 - Dimethyl - N - n - hexadecyl - N - (#- methyl - sulphonylamino) - ethylaniline is made by reacting 3: 5-dimethyl-N-n-hexadecylaniline with # - (methylsulphonylamino) ethyl bromide. n - Decylamino - formylaminodurene (i.e. 2: 3: 5: 6 - tetramethyl - 4 - formylamino - N- n-decylaniline) is made by reacting n-decyl bromide with amino-formylaminodurene made by reducing with H 2 /Raney Ni nitro-formylaminodurene obtained by heating nitroaminodurene with formic acid. |
