Patent ID: 6977299

Claim:
A method for making an acylamide of the formula, comprising the steps of: (a) effecting reaction in an aromatic organic solvent between an o-nitrophenol and a haloketone in the presence of an acid acceptor, an effective amount of an alkali metal halide, and a phase transfer catalyst, to form an o-nitrophenoxyketone of the formula, (b) hydrogenating the o-nitrophenoxyketone of (a) in the presence of an effective amount of a hydrogenation catalyst to produce a benzoxazine of the formula, and, (c) acylating the benzoxazine of (b) with an acylhalide having the formula, in the presence of an acid acceptor, wherein R is a C( 1-8 ) monovalent organo functional radical, R 1 is a C( 1-8 ) monovalent radical selected from the group consisting of alkyl and alkoxyalkyl, and R 2 –R 5 can be the same or different, and are selected from the group consisting of hydrogen, and C( 1-8 ) monovalent alkyl and alkoxyalkyl radicals, and X is halogen.
