Participants

Reaction Steps

A mixture of 1H-pyrrolo[2,3-b]pyridine-3-carbothioic acid amide (2.53 g, 14.37 mmol), bromopyruvic acid (2.4 g, 14.37 mmol) in ethanol (50 mL) was refluxed for 2 h. The solution was left at room temperature for 16 h and precipitated solid was filtered to give 2-(1H-pyrrolo[2,3-b]pyridin-3-yl)-thiazole-4-carboxylic acid (3.5 g, 100%) as a yellow solid MS 246 (M+1).
