Trimethylsilylmethyl Azide → 5-Pyridin-2-yl-3-trimethylsilanylmethyl-3H-[1,2,3]triazole-4-carboxylic acid ethyl ester

참여 물질

반응 단계

To a solution of pyridin-2-yl-propynoic acid ethyl ester (1.25 g, 7.14 mmol) in benzene (22 mL) was added azidomethyl-trimethyl-silane (1.11 g, 8.56 mmol) and the reaction mixture was refluxed under nitrogen for 72 h. The mixture was then evaporated and purification by chromatography [silica, 0 to 50% ethyl acetate in heptane then HPLC (Chiralpak AD, ethanol in heptane)] afforded the title compound (477 mg, 23%) as a yellow oil. MS: m/e=305.2 [M+H]+.
