10470] To a flame dried 500 mE RB flask, freshly activated Mg turnings (9 g) were added and the flask was equipped with a magnetic stir bar, an addition thnnel and a reflux condenser. This set-up was degassed and flushed with argon and 100 mE of anhydrous ether was added to the flask via syringe. The bromide 3 (51.3 g, 250 mmol) was dissolved in anhydrous ether (100 mE) and added to the addition thnnel. About 5 mE of this ether solution was added to the Mg turnings while stirring vigorously. An exothermic reaction was noticed (to confirmlaccelerate the Grignard reagent formation, 5 mg of iodine was added and immediate decolorization was observed confirming the formation of the Grignard reagent) and the ether started refluxing. The rest of the solution of the bromide was added dropwise while keeping the reaction under gentle reflux by cooling the flask in watet Afier the completion of the addition the reaction mixture was kept at 35C. for 1 hour and then cooled in ice bath. Ethyl formate (9 g, 121 mmol) was dissolved in anhydrous ether (100 mE) and transferred to the addition thnnel and added dropwise to the reaction mixture with stirring. An exothermic reaction was observed and the reaction mixture started refluxing. After the initiation of the reaction the rest of the ethereal solution of formate was quickly added as a stream and the reaction mixture was stirred for a further period of 1 h at ambient temperature. The reaction was quenched by adding 10 mE of acetone dropwise followed by ice cold water (60 mE). The reaction mixture was treated with aq. H2S04 (10% by volume, 300 mE) until the solution became homogeneous and the layers were separated. The aq. phase was extracted with ether (2×200 mE). The combined ether layers were dried (Na2 SO4) and concentrated to afford the crude product which was purified by colunm (silica gel, 0-10% ether in hexanes) chromatography.
