Reaction Steps

To a solution of 1.63 of 9e in 20 ml of diethyl ether and 1.4 ml of triethyl amine was added, at 0° C., 0.8 ml of ethyloxalyl chloride. The reaction mixture was stirred for ½ h and then poured into water and extracted with ethyl acetate. The extract was washed with 1M aq. K2CO3 and water, dried and concentrated. The residue was chromatographed over silica gel, using a gradient of heptane/ethyl acetate as eluent, to provide 950 mg of 9f.
