Reaction Steps

A mixture of 2a (3.42 g, 15.0 mmol) and pyridinium p-toluenesulfonate (188 mg) in ethanol (100 mL) was heated at 40°-50° C. with stirring for 10 hr. The mixture was diluted with toluene and a small amount of triethylamine was added to the mixture. After evaporation of ethanol, the residue was poured into brine and extracted with ethyl acetate until none of the product remained the in aqueous layer. The combined organic layers were washed with brine, and dried over sodium sulfate. Filtration and concentration gave 2.53 g of an oily material, which was purified by column chromatography (silica gel 20 g, ethyl acetate in n-hexane, 20-50%) to give 1.88 g (86.9%) of 3a, as a colorless oil.
