실험 절차

To a solution of ethyl thiazolo[4,5-c]pyridine-2-carboxylate (R-3) (5 g, 24 mmol) in ethanol (100 mL) was added NaBH4 (0.9 g, 24 mmol) in portions at 0° C. The suspension was stirred at room temperature for 1 h, and then concentrated. The resulting residue was dissolved in EtOAc, washed with water. The organic layer was separated, dried over Na2SO4, concentrated in vacuo and purified by chromatography on silica gel to give the title compound. MS (m/z): 167 (M+1)+.
