Procedure

The 2-((benzyloxy)methyl)-5,5-dimethyl-1,3-dioxane (7.6 g, 32.2 mmol) obtained by the step (1a) was mixed with 20% palladium hydroxide (700 mg) and ethyl acetate (70 ml). The mixture was stirred in a hydrogen atmosphere overnight. The reaction mixture was allowed to stand for further 5 days in the same hydrogen atmosphere. The reaction vessel was purged with nitrogen, the catalyst was filtered off, and the solvent was distilled off to obtain the title compound (4 g, yield: 85%) as a white solid.
