Abstract

4 : 41 - [p - Di - (carbethoxymethyl) - amino - benzylidene] - bis - 1 - (41 - phenoxy - 31 - sulpho - phenyl - 3 - heptadecyl - 5 - pyrazolone is prepared by reacting 1-(41-phenoxy-31-sulpho) -phenyl-3-heptadecyl-5-pyrazolone in aqueous methanol containing sodium hydroxide with p-di-(carbethoxymethyl)-aminobenzylidene oxime, itself prepared by refluxing p-di-(carbethoxymethyl)-aminobenzaldehyde with hydroxylamine hydrochloride in aqueous ethanol containing sodium carbonate. The first-mentioned compound may also be obtained by direct reaction with the aldehyde. A bis-compound may also be prepared by reacting the pyrazolone with p-hydroxybenzaldehyde. Specifications 486,848, 651,059, [both in Group XX], 673,091 and 723,171, [Group XX], are referred to.
