실험 절차

Under ice-cooling, to a solution of 4,5-dihydronaphtho[1,2-d][1,3]thiazol-2-amine (1.50 g, 7.4 mmol) in pyridine (20 mL) was added propionyl chloride (1.03 g, 11 mmol), and the mixture was stirred at room temperature for 2 hrs. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with water and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=3:1) to give the title compound (1.75 g, yield 91%) as a powder.
