Reaction Steps

The title compound was prepared from 3-(2,4-dichloro-phenyl)-1,1,1-trifluoro-2-pyridin-4-yl-butan-2-ol (Example 11) by O-methylation: 3-(2,4-dichloro-phenyl)-1,1,1-trifluoro-2-pyridin-4-yl-butan-2-ol (45 mg) was dissolved in dry DMF (4 mL) under argon at room temperature. To the mixture was added sodium hydride (8.4 mg, 50% in mineral oil) and the mixture was allowed to stir for 30 minutes. Iodomethane (22 mg, 0.01 mL) was added and stirring was continued for 1 hour at room temperature. The mixture was poured into ice water and extracted with ethyl acetate. The organic layer was washed with brine, dried over Na2SO4 and evaporated. The residue was purified by flash chromatography (20 g silica gel, gradient of ethyl acetate in heptane (10 to 40%) to give the desired material as light yellow oil (28 mg). MS (m/e)=364.1 [MH+].
