実験手順

Under ice-cooling, to a solution of N-(4,5-dihydronaphtho[1,2-d][1,3]thiazol-2-yl)propanamide (1.70 g, 6.6 mmol) in tetrahydrofuran (30 mL) was added lithium aluminum hydride (749 mg, 20 mmol), and the mixture was stirred at room temperature for 3 hrs. Sodium sulfate 10 hydrate (9.6 g, 30 mmol) was added, and the mixture was stirred at room temperature for 1 hr. Insoluble material was filtered off, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4:1) to give the title compound (1.32 g, yield 82%) as a yellow powder.
