Abstract

PURPOSE: To prepare an N-substituted derivative of an aromatic aminohydroxy compound, in high selectivity and yield, by using 1mol of an active halogenated compound having n-halocarbonyl groups, etc. and more than n-moles of an aromatic aminohydroxy compound.
CONSTITUTION: The N-substituted aromatic aminohydroxy compound of formula V[Ar is group of formula II, formula III, etc. (R1 and R2 are H, halogen, etc.; a is 1W4; b is 1W6; etch R2 bounds to the residual 6 carbon atoms of the naphthalene ring)]is prepared by the selective N-substitution of the aromatic aminohydroxy compound of formulaIcomprising the reaction of 1mol of an active halogen compound of formula IV (D is 1W20C n-valent organic group which may contain halogen, N, etc.; Y is CO or SO2; X is halogen; n is 1W10) with more than n moles of the compound of formulaI, usually at -50W+150°C. A high selectivity can be attained by reacting at -20W+100°C.
