Methyl 3-hydroxythiophene-2-carboxylate yog cov organic compound uas muaj cov methyl pawg txuas nrog lub nplhaib thiophene. Nws yog ib qho precursor rau cov tshuaj amiloride, uas yog siv los kho cov ntshav siab thiab edema.
Lub compound tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm hydrogen chloride nrog cawv hauv alkaline. Nws tuaj yeem raug tsim los ntawm 3-chlorothiophene-2-carboxylic acid thiab methanol hauv dilute hydrochloric acid.
Tsis tas li ntawd, nws tuaj yeem npaj tau los ntawm chlorination ntawm methyltetrahydrothiophene -2-carboxylic acid nyob rau hauv muaj cov tooj liab (II) oxide ua catalyst. Lub compound tau decarboxylated ntawm 200 degree thiab ces reacted nrog chloroform nyob rau hauv refluxing tej yam kev mob los tsim amiloride.
