The reaction mixture was stirred at room temperature under a hydrogen atmosphere until 1 equivalent of hydrogen was absorbed. The catalyst was removed by filtration over diatomaceous earth. The solvent was evaporated, yielding 3.3 g (67%) of Intermediate 30 as an oil that was used without further purification.
