Processes for preparing an amine compound by catalytically hydrogenating a precursor nitrile compound. In a particular aspect, the present hydrogenation process occurs in a dipolar organic solvent in the presence of a palladium/carbon catalyst and a strong anhydrous protic acid. In a further aspect, the preferred embodiment relates to a process for deprotecting a compound to produce an amine compound. In yet a further aspect, the preferred embodiment relates to amine products produced by the present processes. These amine products may be used for a variety of purposes.
通过在存在钯/碳催化剂和强无水质子酸的情况下,在偶极有机溶剂中催化氢化前体腈化合物的过程。在一个特定方面,目前的氢化过程发生在一个偶极有机溶剂中,在钯/碳催化剂和强无水质子酸的存在下。在另一个方面,首选实施例涉及一种去保护化合物以产生胺化合物的过程。在另一个方面,首选实施例涉及通过目前的过程产生的胺产品。这些胺产品可以用于各种目的。
