  • Method for making acylamides by synthesizing and acylating benzoxazines
    Patent number: 7161001
    Abstract: A method is provided for synthesizing acylamides, useful as protectant for cultivated plants. A benzoxazine, such as 3,4-dihydro-3-methyl-2H-1,4-benzoxazine, is made in a stepwise manner by initially forming an o-nitrophenoxyketone by reacting a haloketone and a nitrophenol. The o-nitrophenoxyketone is hydrogenated to form the corresponding benzoxazine, which is thereafter acylated with an acylhalide to produce the acylamide, such as 4-dichloroacetyl-3,4-dihydro-3-methyl-2H-1,4-benzoxazine.
    Type: Grant
    Filed: August 15, 2005
    Date of Patent: January 9, 2007
    Assignee: Syngenta Crop Protection, Inc.
    Inventors: Catherine Munson, legal representative, Michael Allen Oliver, Heinz Peter Schwemlein, Robert Eugene Munson, deceased
