Reaction Steps

2-Amino-4-methyl-5-acetylthiazole (3 g, 19.2 mmol) is dissolved in DMF (30 mL). CDI (3.5 g, 21.1 mmol) is added and the mixture is stirred at RT for 3 h. Ammonia 0.5 N in dioxane is added (60 mL, 30 mmol) is added and the mixture is stirred for 2 days in a closed system. The resulting precipitate is recovered by filtration, washed with petroleum ether and dried under vacuo, affording N-(5-acetyl-4-methyl-1,3-thiazol-2-yl)urea as colorless solid (1.5 g, 39%).
