Procedure

Under argon atmosphere, the product from step 2 herein, 2.74 g (13.03 mmol) was dissolved in 55 ml of dry ether. Dimethoxy methane 1.65 ml (19.55 mmol) and boron trifluoro etherate 4.9 ml (39.09 mmol) were then added to this solution. The obtained reaction mixture was left stirring overnight. The reaction mixture was quenched using aqueous NaHCO3 and extractions were done using ether. The combined organic extracts were dried over Na2SO4, filtered, and the solvent was removed. The residue was purified by flash chromatography using hexanes-ethyl acetate (80:20) and (70:30) as eluent. The isolated titled product was a white solid (1.56 g; 54%).
