Reaction Steps

To a solution of [4-(3,5-dimethylphenyl)-5-(4-pyridyl)-1,3-thiazol-2-yl]amine (0.50 g, 1.78 mmol) and 4-dimethylaminopyridine (0.06 g, 0.51 mmol) in N,N-dimethylacetamide (5 mL) was added acetyl chloride (0.21 g, 2.67 mmol) and the mixture was stirred at 80° C. for 14 h. To the reaction mixture was poured aqueous sodium hydrogencarbonate. The precipitated solid was collected by filtration. The obtained solid was washed with water and dried. The crude crystals were recrystallized from ethanol to give the title compound (0.17 g, yield 29%).
