该中间体在本合成路线中的序号：(XIII)After hydrogenation of the enamine double bond of (XI) to give (XII), alkylation of the hydroxyl group of (XII) in the presence of KH provided the methyl ether (XIII). The dimethoxybenzyl protecting group of (XIII) was then cleaved with trifluoroacetic acid to give (XIV). This was finally dehydrogenated to the title compound employing DDQ or (PhSeO)2O as the oxidant reagents.
