실험 절차

By the method described in Example 10, Step B, N-t-butylbenzenesulfonamide [G. Lombardino, J. Org. Chem., 36, 1843 (1971)] was deprotonated with n-butyllithium, and the resulting dianion was reacted with triisopropyl borate and worked up with acid to give the title compound, which was used directly in the next step without further purification.
