Reaction Steps
An alternative procedure is as follows: To a solution of 2-Iodo-5-(trifluoromethyl)benzaldehyde (EXAMPLE 80, Step A, 9 g) in THF (100 mL) and water (10 mL) at 0° C. was added NaBH4 (0.5 g). The reaction was stirred 30 minutes. To the reaction mixture was added dilute aqueous HCl (cautiously). The mixture was extracted with ether and the ether layer was washed with water, then brine. The ether layer was then dried over anhydrous MgSO4, filtered and concentrated. The material is chromatographed on SiO2 using a step gradient of 1:3 CH2Cl2/hexanes, then 1:1 CH2Cl2/hexanes, then 100% CH2Cl2 to afford [2-iodo-5-(trifluoromethyl)phenyl]methanol as a white solid.
