실험 절차

To a solution of 4-fluoro-3-[[2-fluoro-3-(3-fluorophenyl)-5-methyl-phenyl]methylamino]-2-methyl-phenol (180 mg, 0.5 mmol, 1.0 eq) in DMF (3 mL) was added Cs2CO3 (246 mg, 0.75 mmol, 1.5 eq). The reaction was stirred for 30 min at room temperature then isopropyl 2-bromoacetate (99 mg, 0.55 mmol, 1.1 eq) was added. The reaction was stirred a further h then diluted with water and extracted with EtOAc. The organic extract was washed with brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography (petroleum ether:EtOAc, 1:0 to 25:1) to give the title compound as a colorless oil (100 mg, 43%).
