반응 단계
2-Chloro-6-methyl-nicotinic acid (3.58 g, 20.86 mmol) was dissolved in DMF (34 mL). MeI (5.8 mL, 93.88 mmol) and K2CO3(7.78 g, 56.33 mmol) were added thereto, and the mixture was stirred at room temperature for 2 hours. The reactant was distilled under reduced pressure to remove the solvent and extracted with EtOAc. The organic layer was dried with MgSO4, filtered and concentrated under reduced pressure. The obtained residue was purified by column chromatography (eluent EtOAc/Hex=1/2) to obtain the title compound (3.68 g, 94%).
