Reaction Steps

To a solution of the ethyl 4-iodobenzoate (1.21 ml, 7.24 mmol) in tetrahydrofuran (12 ml) at −40° C. was added isopropylmagnesium chloride lithium chloride complex (6.13 ml, 7.97 mmol, 1.3M in tetrahydrofuran) dropwise. The mixture was stirred for approximately 1 hour whereupon the 4,4,4-trifluorobutanal (0.761 ml, 0.724 mmol) was added dropwise. The mixture was stirred at −40° C. for 15 minutes and slowly warmed to ambient temperature over 12 hours. The reaction was quenched with aqueous 1.0M hydrochloric acid and the aqueous layer was extracted with ethyl acetate (3×). The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo. The alcohol was used without further purification.
