Reaction Steps

Among the reaction product from Example 1, those fractions from the fractionation by silica gel column chromatography (ethyl acetate/hexane) that are low polarity elution fractions (demonstrating high Rf value on TLC) were collected, and the title compound (29 mg) was obtained as a colorless solid.
