Reaction Steps

To a solution of 3-[[5-(3-fluorophenyl)-2-methoxy-3-methyl-phenyl]methylamino]-2,4-dimethyl-phenol (115 mg, 0.31 mmol, 1.0 eq) in acetone (4 mL) was added Cs2CO3 (154 mg, 0.47 mmol, 1.5 eq). The reaction mixture was stirred for 30 min at room temperature then isopropyl bromoacetate (68.4 mg, 0.38 mmol, 1.2 eq) was added. The reaction mixture was stirred at room temperature for a further 2 h then poured into water and extracted with EtOAc. The combined organic extracts were washed with water and brine, dried (Na2SO4), filtered and evaporated in vacuo. The residue was purified by column chromatography (petroleum ether:EtOAc 30:1 to 20:1) to give the title compound as a colorless oil (155 mg, 100%).
