실험 절차

Lithium aluminum hydride (900 mg) was added to anhydrous tetrahydrofuran (20 ml) and a solution of 2-(N-methyl-2-propynylamino)-4-methoxycarbonylthiazole (h) (5.0 g) in tetrahydrofuran (30 ml) was added dropwise thereto with stirring under ice-cooling. The mixture was refluxed for 2 hours, to which water was carefully added under ice-cooling, and evaporated to remove the tetrahydrofuran. The residue was extracted with chloroform. The extract was washed with water, dried and recrystallized from ether-hexane to give 2-(N-methyl-2-propynylamino)-4-hydroxymethylthiazole (i) (3.75 g, yield 86.5%): mp. 69°-70° C.
