| titleOfInvention | Production of diphenylamine compound |
| abstract | PURPOSE: To produce the titled compound which is an intermediate of a fluoran compound useful as a color-developing material for pressure-sensitive copying paper, etc., in high yield, by reacting a bromophenol derivative with an aniline derivative, and hydrolyzing the resultant compound to effect the deacylation. n CONSTITUTION: The bromophenol derivative of formula II (R 1 is methyl or ethyl; R 2 is H, halogen, methyl, etc.) is made to react with the aniline derivative of formula III (R 3 is H, Cl, acetyl etc.; R 4 is H or lower alkyl) in the presence of an alkali such as K 2 CO 3 , copper powder, and iodine. The resultant N-acyldiphenylamine compound of formula IV is deacylated by hydrolysis to obtain the objective compound of formula I . n EFFECT: Since the reaction steps are decreased compared with a conventional process, the reaction operation can be facilitated, and the objective compound can be produced at a low cost. n COPYRIGHT: (C)1985,JPO&Japio |
