반응 단계
A mixture of 3-methyl-1H-1,2,4-triazole (5.0 g, 60.2 mmol), 1-chloro-2-methoxy-4-nitrobenzene (11.3 g, 60.2 mmol), and KOH flakes (3.4 g, 48.1 mmol) in anhydrous DMSO (50 mL) was heated at 80° C. for 6 h. The reaction mixture was allowed to cool to rt and was poured into 800 mL of water with vigorous stirring. The aqueous mixture was extracted with EtOAc (3×200 mL). The combined organics were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude residue was purified using silica gel chromatography (0-2% MeOH/chloroform, linear gradient) to afford 1-(2-methoxy-4-nitrophenyl)-3-methyl-1H-1,2,4-triazole (3.7 g, 26% yield). LC-MS (M+H)+=235.2.
