Patent number: 6982331Abstract: The invention provides a process for synthesizing chlorinated pyrimidines. The process includes reacting imidoyl chloride compounds with phosgene (COCl2). The imidoyl chloride compounds can be supplied as starting materials or can be produced by reacting organic amides with phosgene or reacting organic nitrites with hydrogen chloride. Phosgene may be replaced by equivalent reagents. The chlorinated pyrimidines, such as 4,6-dichloropyrimidine, can be used to synthesize other compounds useful in a variety of compositions, such as fungicides, pesticides, and pharmaceuticals.Type: GrantFiled: June 27, 2003Date of Patent: January 3, 2006Assignee: Syngenta Crop Protection, Inc.Inventors: Timothy J.

Patent number: 6977299Abstract: 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-dichloroacetyl-3,4-dihydro-3-methyl-2H-1,4-benzoxazine.Type: GrantFiled: May 21, 2001Date of Patent: December 20, 2005Assignee: Syngenta Crop Protection, Inc.Inventors: Catherine Munson, legal representative, Michael Allen Oliver, Heinz Peter Schwemlein, Robert Eugene Munson, deceased
