Reaction Conditions:

with iodine;magnesium in diethyl ether;Inert atmosphere;Reflux;

Steps:

Preparation of arylmagnesium bromides

General procedure: A solution of aryl bromide (0.3 mol) (see Table 1) in diethyl ether (~215 mL) was added to a mixture of Mg turnings (7.29 g, 0.3 mol), diethyl ether (~17 mL), and a catalyst (several iodine crystals) under argon with stirring at such a rate that the ether was boiling, then the mixture was refluxed for 1-1.5 h. Since 1-bromo-2,4-dichlorobenzene (the starting compound for the synthesis of a-hydroxy ester 3e) did not react with magnesium under these conditions, the Grignard reaction for it was carried out in the presence of a large amount of iodine and dibromoethane (4 mL) upon reflux for 2.5 h.
