반응 단계
To a solution of 2,4,6-trichloropyridine (4.5 g) in methanol was added sodium methoxide (25% in methanol, 6.8 mL) at room temperature. The mixture was stirred for 12 h then poured into ethyl acetate/water and separated. The organic layer was washed with water, brine and dried over magnesium sulfate. Upon evaporating, the residue was purified by crystallization (100% hexanes) to give title compound as solid (3.1 g).
