| abstract | 1499129 Naphthamides and pyrazolones FUJI PHOTO FILM CO Ltd 20 June 1975 [20 June 1974] 26412/75 Heading C2C [Also in Division G2] 1 - Hydroxy - 4 - nitro - N - [γ - (2,4 - di - tert amylphenoxy)propyl] - 2 - naphthamide is prepared by nitration of 1-hydroxy-N-[γ-(2,4-ditert. - amylphenoxy)propyl] - 2 - naphthamide. 1 - Hydroxy - 4 - amino - N - [γ - (2,4 - di - tert.- amylphenoxy)propyl] - 2 - naphthamide is prepared by reduction of the corresponding nitro compound above with iron in aqueous acetic acid. 1 - Hydroxy - 4 - isothiocyanato - N - [γ- (2,4 - di-tert. - amylphenoxy)propyl]- 2 - naphthamide is prepared by adding a pyridine solution of the above amino compound to dicyclohexylcarbodiimide, pyridine and carbon disulphide at - 10‹ C., evaporating off the solvent, adding ethyl acetate, filtering, concentrating the filtrate and precipitating the product in acetonitrile. 1 - Hydroxy - 4 - (3 - allyl - 5 - oxo - 2 - thioxoimidazolidin - 1 - yl) - N - [γ - (2,4 - di - tert.- amylphenoxy)propyl] - 2 - naphthamide is prepared by refluxing the above isothiocyanato compound with ethyl acetate and ethyl allylaminoacetate. 1 - (2,4,6 - trichlorophenyl) - 3- [3 - (2,4 - di - tert. - amylphenoxy - acetamido)- benzamido] - 4 - bromo - 5 - pyrazolone is prepared by adding bromine dropwise to the corresponding 4-unsubstituted compound in acetic acid. 1,(2,4,6-Trichlorophenyl)-3-[3-(2,4- di - tert. - amylphenoxy - acetamido)benzamido]- 4 - (4 - phenyl - 5 - thioxo - tetrazolin - 1 - yl) - 5- pyrazolone is prepared by reacting the above bromo compound with a mercuric salt of 1- phenyl-5-mercaptotetrazole in dimethylformamide. These compounds are used as colour couplers in photographic silver halide materials. |
