Chloroacetic Acid → 1(2H)-Pyrazineacetic acid, 2-oxo-

참여 물질

반응 조건

반응 단계

To Pyrazin-2(1H)-one (0.333 g, 3.47 mmol) was added 5 N sodium hydroxide solution (2.1 ml) followed by chloroacetic acid (0.524 g, 5.54 mmol). The reaction mixture was heated at 100° C. for 2 h. After cooling to ambient temperature, 2 N hydrochloric acid (3.5 ml) was added and the reaction mixture was directly purified by reverse phase HPLC (TMC Pro-Pac C18; 0-40% 0.1% trifluoroacetic acid in acetonitrile/0.1% trifluoroacetic acid in water gradient). The pure fractions were lyophilized overnight to yield the title compound as a yellow solid. LC/MS 155.2 (M+1)+.
