The compound 17 (1.11 g) was weighed and poured into a 100-ml round-bottomed flask, and 10 ml of trifluoroacetic acid was added and stirred, to obtain an orange-colored homogenous solution. After 0.9 ml of triethylsilane was added to generate a white-colored precipitate, the supernatant solution (transparent) was distilled away under reduced pressure. The solid obtained was purified by chromatography, and 0.6 g of the compound e, which was a white solid, was obtained.
