Reaction Steps

A solution 1-(5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-chloro-ethanone (0.32 g, 1.17 mmol) and thio urea (0.097 g, 1.28 mmol) in ethanol (4 mL) was stirred at 80° C. for 1.5 hours. The resulting precipitate was filtered, washed with MeOH, and dried under vacuum to give 4-(5-Bromo-1H-pyrrolo[2,3-b]pyridin-3-yl)-thiazol-2-ylamine (0.34 g, 99% yield).
