Unequivocal methods for the specific preparation of 4- or 5-acyl-2-aminophenols are reported. 5-Acyl-2-aminophenols are obtained by ring opening with dilute sodium hydroxide of 2(3H)-benzoxa-zolinones acylated at position 6. 4-Acyl-2-aminophenols are obtained by acylation of 2-acetamidophenol in the presence of aluminum chloride/dimethylformamide followed by a deprotection of the amino group.
