Abstract
1 - (o - Amino - p - sulphophenyl) - 3 - stearyl - 5 - pyrazolone is prepared by mixing 2-nitrophenyl-hydrazine-4-sulphonic acid with a -stearoyl ethyl acetate and sodium acetate in isopropanol, adding caustic soda and heating. The nitrocompound formed is reduced to the corresponding amino compound with catalytic hydrogen under pressure. Instead of the above hydrazine, 2 - b - chloroethylamino - 5 - sulphophenyl - hydrazine may be employed to give the corresponding 1 - (2 - b - chloroethylamino - 5 - sulpho - phenyl)-pyrazolone. 1 - [2 - (g - sulphopropylamino) - 4 - sulpho - phenyl]-3-stearyl-5-pyrazolone is prepared by reacting 1 - (2 - amino - 4 - sulphophenyl) - 3 - stearyl-5-pyrazolone with propane sultone. The latter pyrazolone also may be reacted with butane sultone, 4-chloro-3-nitrobenzene-1-sulphonic acid, chloracetic acid, 2-chlorobenzthiazole, m-nitrobenzyl chloride, acrylonitrile, benzoyl chloride, phenyl isocyanate or benzene sulphonyl chloride, to give 1-(2-substituted amino - 4 - sulphophenyl) - 3 - stearyl - 5 - pyrazo - lones wherein the substituent in the amino group is g -sulphobutyl, 2-nitro-4-sulphophenyl (the nitro group of which may be reduced to the corresponding amine), carboxymethyl, 2-benzthiazolyl, m-nitro-benzyl (the nitro group of which may be reduced to the corresponding amine), b -cyanoethyl, benzoyl, phenylcarbamyl and phenylsulpho. 1 - { 2- [2 (g - sulphobutylamino) - 4 - sulpho - phenylamino] - 4 - sulphophenyl} - 3 - stearyl - 5 - pyrazolone is prepared by refluxing 1-[2-(2-amino - 4 - sulphophenylamino) - 4 - sulpho - phenyl]-3-stearyl-5-pyrazolone with butane sultone in ethanol. 1 - {2 - [m - (g - sulphobutylamino) - benzyl - amino] - 4 - sulphophenyl} - 3 - stearyl - 5 - pyrazolone is prepared by refluxing 1-[2-(m-aminobenzylamino) - 4 - sulphophenyl] - 3 - stearyl-5-pyrazolone with butane sultone in ethanol. Bis N, N1 - [2 - (3 - stearyl - 5 - keto - 1 - pyrazolinyl) - 5 - sulphophenyl] ethylene diamine is prepared by refluxing 1-(2-amino-4-sulphophenyl)-3-stearyl-5-pyrazolone and ethylene dibromide in ethanol.
