실험 절차

Sodium ethanethiol (0.108 g, 1.29 mmol) was added to a solution of 2-(2-oxo-2H-pyridin-1-yl)-anisole (0.100 g, 0.497 mmol) in DMF (2 mL), and the reaction mixture was heated at 100° C. for 3 hr. The reaction mixture was partitioned between CHCl3 and saturated aqueous ammonium chloride and treated with 8N HCl (pH=1). The organic layer was separated, washed with H2O, brine, dried (Na2SO4), filtered, concentrated, and taken up in EtOAc, then extracted with 2% NaOH solution. The aqueous basic layer was acidified with 10% HCl solution, then extracted with EtOAc, the organic layer washed with brine, dried (Na2SO4), filtered, and concentrated to give the desired product.
