YieldReaction ConditionsOperation in experiment
Step 1. 1- (2-Chloro-4- (trifluoromethyl) phenyl) ethan-1-ol:DMSO (7.73 ml, 109 mmol) was added to a -78 solution of oxalyl chloride (4.77 ml, 54.5 mmol) in dichloromethane (100 ml) . The mixture was stirred for 10 minutes before the addition of (2-chloro-4- (trifluoromethyl) -phenyl) methanol (7.65 g, 36.3 mmol) as a solution in dichloromethane (100 ml) . This mixture was stirred for 30 minutes at-78 and then treated with triethylamine (25.3 ml, 182 mmol) . The resulting mixture was stirred for 20 minutes at-78 and then warmed to RT and stirred for 1 h. The reaction was then quenched with saturated NaHCO3solution and the aqueous layer was extracted with dichloromethane. The organic extracts were combined and washed with 1N HCl, water, and then dried over Na2SO4. This mixture was filtered and concentrated. The crude aldehyde was then dissolved in THF (85 ml) and the solution was cooled to 0 before the addition of methylmagnesium bromide (15.74 ml, 47.2 mmol) . After 5 minutes the reaction was quenched with saturated NH4Cl solution and the product was extracted with ethyl acetate. The organic extract was dried over Na2SO4, filtered, and concentrated. The product was purified by silica gel chromatography (0-30 ethyl acetate in hexanes) to furnish the title compound.1H NMR (500 MHz, CDCl3) delta: 7.78 (d, J 8 Hz, 1H) , 7.62 (s, 1H) , 7.58 (d, J 8 Hz, 1H) , 5.34 (q, J 6 Hz, 1H) , 2.15 (broad, 1H) , 1.53 (d, J 6 Hz, 3H) .
