A solution of 552 mg (2 mmol) of ethyl 4-iodobenzoate in 20 ml of THF was cooled to −40° C. and 1.06 mmol of diisopropylmagnesium in methyl tert-butyl ether were added. After 1 h at −40° C. 233 mg (2.2 mmol) of benzaldehyde were added. After 3 h, the reaction mixture was hydrolyzed and the org. phase was concentrated. Chromatography of the crude product with 4/1 pentane/ether afforded 460 mg (90%) of the alcohol.
