Participants

Reaction Steps

To a solution of 4-fluoro-3-[[2-fluoro-5-(3-fluorophenyl)phenyl]methylamino]-2-methyl-phenol (200 mg, 0.58 mmol, 1.0 eq) in DMF (6 mL) was added Cs2CO3 (283 mg, 0.87 mmol, 1.5 eq). The reaction mixture was stirred for 1 h at room temperature, then ethyl 2-bromoacetate (117 mg, 0.70 mmol, 1.2 eq) was added. The reaction mixture was stirred for a further 1 h then poured into water and extracted with EtOAc. The organic extract was washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue obtained was purified by column chromatography to give the title compound as an oil (200 mg, 80%).
