ABSTRACT:
This invention relates to p-acylaminophenoxycarbamates having the formula ##STR1## where R.sub.1 and R.sub.2 are each independently hydrogen, loweralkyl, aryl and arylloweralkyl; R.sub.3 is hydrogen, loweralkyl, arylloweralkyl; R.sub.4 is hydrogen, loweralkyl, formyl, alkylcarbonyl, arylloweralkyl, phenylcarbonyl, arylloweralkylcarbonyl, substituted phenylcarbonyl, pyridylcarbonyl, and substituted pyridylcarbonyl with the proviso that if R.sub.4 contains a carbonyl group directly attached to the oxygen of the N-O moiety, R.sub.3 cannot be hydrogen; or R.sub.3 and R.sub.4 taken together from a heterocyclic ring selected from the group consisting of imidazole or loweralkylimidazole; X is hydrogen, halogen, hydroxy, loweralkyl, loweralkoxy, nitro, amino or trifluoromethyl; and p is an integer selected from 0 and 1; the pharmaceutically acceptable acid addition salts thereof, and where applicable, the geometric and stereoisomers and racemic mixtures thereof. The compounds of this invention display utility as analgesics.
