Procedure

To tributyltin chloride (652 mg, 2.00 mmol, 1.00 equiv) in THF (2 mL) at 23° C. was added 4-methoxyphenylmagnesium bromide (0.50 M in THF, 8.0 mL, 4.0 mmol, 2.0 equiv). After stirring for 1.0 hr at 60° C., the reaction mixture was cooled to 0° C. and quenched with saturated aqueous NH4Cl (10 mL), and Et2O (10 mL) was added. The phases were separated and the aqueous phase was extracted with Et2O (2×10 mL). The combined organic phases were washed with brine (10 mL) and dried (Na2SO4). The filtrate was concentrated in vacuo and the residue was purified by fractional distillation to afford 637 mg of the title compound as a colorless oil (80% yield).
