Reaction Steps

Ethyl 2-oxo-2-(4-(trifluoromethyl)phenyl)acetate (500 mg, 2.03 mmol) is dissolved in absolute EtOH (10 mL) and cooled at 0° C. under N2. NaBH4 (38.4 mg, 1.02 mmol) is added in two portions and the resulting suspension is allowed to warm to RT and stirred for 45 minutes. The solvent is evaporated, the resulting residue is diluted with Et2O and cool water is added. The organic layer is separated, washed with water and brine, dried over Na2SO4, filtered and evaporated obtaining intermediate I149 as a colorless oil (440 mg, 87% yield).
