Procedure
A solution of 3-chlorobenzaldehyde (1.4 g, 10 mmol) in THF (10 mL) was cooled to −10° C., then 2.0 M n-butylmagnesium chloride (10 mL) was added. The reaction was allowed to warm to RT under N2 overnight. Next day the reaction was cooled to 0−5° C., water (5 mL) was added, followed by 2N HCl—Et2O partition. The organic layer was washed with brine, then dried over Na2SO4. After filtration and concentration the crude material was purified by chromatography using 9/1 hex/EtOAc. Recovered 1.25 g (63%).
