Reaction Steps

General Procedure HH: To a solution of 1-iodo-2-(trifluoromethyl)benzene (1.5 g, 5.5 mmol) in THF (10.0 mL) was added 2.5 M of n-BuLi in hexane (2.2 mL) at −78° C. and stirred for 10 min. Propylene oxide (370 mg, 6.4 mmol) was added to the reaction mixture at −78° C. and slowly warmed to rt. The reaction mixture was stirred for an additional 30 min. The reaction mixture was quenched with sat. aq. NH4Cl and extracted with EtOAc. The organic layer was washed with brine, dried over anhydrous Na2SO4, and the solvent was removed under reduced pressure to give a yellow oil. The material was purified by silica gel chromatography using Hexane/EtOAc (80:20) as eluent to yield the desired product as a colorless oil. 1H NMR (CDCl3, 400 MHz): δ=1.30 (d, J=6.1 Hz, 3H), 1.46 (d, J=4.3 Hz, 1H), 2.82-3.06 (m, 2H), 4.03-4.12 (m, 1H), 7.32-7.38 (m, 1H), 7.41-7.45 (m, 1H), 7.48-7.53 (m, 1H), 7.67 (d, J=8.1 Hz, 1H).
