반응 단계

A solution of N-(4-iodo-6-methoxypyridin-3-yl)pivalamide (Compound 2, 2.33 g, 7.0 mmol) in 10% H2SO4 (70 ml) was heated to reflux at 120° C. for 5 h. The mixture was cooled to 0° C. and was quenched cautiously with solid NaOH (10 g), extracted with EtOAc (×2). The combined organic layer was washed with brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→30% EtOAc-hexanes) to yield the title compound as off-white solid.
