Abstract
1,265,155. 3 - (2,4,6 - Trimethylphenylacylamino)-2-pyrazolin-5-ones. AGFA-GEVAERT. 20 June, 1969 [18 July, 1968], No. 34339/68. Heading C2C. [Also in Division G2] Novel 1-substituted-2-pyrazolin-5-one colour couplers substituted in the 3-position by a 2,4,6-trimethylphenylcarbonamido or 2,4,6-trimethylphenylsulphonamido group, more particularly couplers of the formula in which X is -CO- or -SO 2 - and R represents an optionally substituted alkyl, aralkyl, aryl or heterocyclic radical or a group -Y-D where Y is a direct bond, -O-, -S-, -SO 2 -, -NHSO 2 -, -SO 2 N(R 1 )-, -CONH, -NHCO- or -N(alkyl)- where R 1 is hydrogen or C 1-5 alkyl and D is a C 5-20 acyclic aliphatic group, are prepared by condensing 2,4,6- trimethylphenylsulphonyl chloride or 2,4,6- trimethylbenzoyl chloride with the appropriate 1 - substituted - 3 - amino - 2 - pyrazolin - 5 - one in an anhydrous solvent and/or in the presence of a base and preferably also in the presence of AlCl 3 . The preparation of a variety of amides is described. The colour couplers are used in photographic materials (see Division G2). 2,4,6-Trimethylbenzene sulphochloride is obtained by treating mesitylene with chlorosulphonic acid. 1-(2-Hexadecyloxy-5-chlorophenyl)- 3-amino-2-pyrazolin-5-one is obtained by condensing 2-hexadecyloxy-5-chloro-phenyl-hydrazine with #-ethoxy-#-aminoacrylic acid ethyl ester.
