Abstract
PURPOSE: To obtain an N-substituted compound of the titled compound useful as an agricultural chemical or drug in high selectivity and in high yield, by reacting an aromatic aminohydroxy compound with an active halogen compound in the presence of an amide type compound.
CONSTITUTION: An aromatic aminohydroxy compound shown by the formula Ho-Ar-NH2[Ar is a group shown by the formulaI or formula II (R1 and R2 are H, halogen, etc.; a is integer of 1W4; b is integer of 1W6; when they are ≥2, plural R1 and R2 may be different or the same; each R2 is linked to any 6C of the rest of naphthalene ring)]is reacted with an active halogen compound shown by the formula III (D is 1W20C n-functional organic group-containing N, etc.; Y is CO, etc.; X is halogen; n is 1W10) in the presence of an amide type compound (e.g., N,N-dimethylacetamide, etc.) in a solvent such as benzene, to give the desired compound shown by the formula IV.
