Reaction Steps

To a solution of 5-[2-(4-bromo-2-chloro-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1H-pyridin-2-one (354 mg) in N,N-dimethylacetamide (4.7 ml) were added powdered potassium carbonate (131 mg) and ethyl iodide (141 mg). The mixture was stirred at room temperature overnight. Water was added and the mixture was extracted with EtOAc. The organic phase was washed with water and dried (MgSO4). The product was purified by chromatography (SiO2, CH2Cl2/MeOH 1:0=>9:1) to give the title compound (324 mg) as a light yellow oil. MS (m/e)=438.2 [M+H+].
