Development of a cost efficient and scaleable process for 2-quinoxalinecarboxylic acid is described. The primarily goals of the development work were to improve the overall yield of the process, to minimize the use of environmentally unacceptable materials, and to obtain a material with a high level of purity. A variety of approaches were examined, and the most efficient method was a condensation of o-phenylenediamine with a monosaccharide followed by a mild peroxide oxidation.

approach toward N-acylated aminotriazoles is reported, enabling the compounds’ screening against FXIIa and thrombin. This approach afforded low-nanomolar FXIIa and thrombininhibitors with no off-targeting of the other tested serine proteases. Selected compounds were shown to be covalent inhibitors of FXIIa and demonstrated anticoagulant properties in vitro, influencing the intrinsic blood coagulation
