Reaction Steps

4.65 g of aldehyde 43 is introduced into 300 ml of methylene chloride under nitrogen, and 7.9 ml of triethylamine and 6.9 g of Eschenmoser's salt are added at 0° C. After 2.5 hours at 0° C., saturated ammonium chloride solution is added, extracted with methylene chloride, washed with sodium chloride solution, dried on sodium sulfate and concentrated by evaporation. The residue is chromatographed on silica gel with ethyl acetate/hexane, whereby 3.84 g of title compound 44 accumulates as a colorless oil.
