Versuchsvorschrift

To a solution of 4-fluoro-3-[[5-(3-fluorophenyl)-2-methoxy-3-methyl-phenyl]methylamino]-2-methyl-phenol (94 mg, 0.25 mmol, 1.0 eq) in acetone (4 mL) at room temperature was added Cs2CO3 (124.4 mg, 0.38 mmol, 1.5 eq). The reaction mixture was stirred for 30 min, then isopropyl bromoacetate (55.3 mg, 1.2 mmol, 1.2 eq) was added and stirring continued for a further 2 h. Water was added and the aqueous layer extracted with EtOAc. The organic extract was washed with water and brinc, dried (Na2SO4), filtered and evaporated in vacuo. The residue was purified by column chromatography (petroleum ether:EtOAc, 20:1) to give the title compound as a colorless oil (65 mg, 54%).
