실험 절차

To a solution of 6-methoxy-4-(3-methylbut-1-ynyl)pyridin-3-amine (Compound 4, 588 mg, 3.1 mmol) in N-methylpyrrolidone (10 ml) was added KOtBu (0.87 g, 7.8 mmol) at room temperature. The mixture was heated to 140° C. for 0.5 h and cooled to room temperature, quenched with H2O, extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→50% EtOAc-hexanes) to yield the title compound as light brown syrup.
