(57) A process for the preparation of an aryloxypropanolamine of the formula
wherein Ar is a carbocyclic or heterocyclic aromatic group and R is an alkyl or substituted alkyl group having 1 to 6 carbon atoms, characterized in subjecting a compound of the formula
to oxidative deavage to a dialdehyde of the formula
which is then made subject to reduction, amination, acetal hydrolysis, and, where required, removal of a nitrogen protective group, to the formation of a compound of formula I, or an acid accition salt thereof, a compound of formula II and the preparation thereof from mannitol.
(57) 一种制备式中Ar为碳环或杂环芳基,R为具有1至6个碳原子的烷基或取代烷基的芳氧基丙醇胺的工艺,其特征在于将式中化合物氧化脱醛成式中的二醛,然后使其还原、胺化、缩醛水解,并在需要时去除氮保护基,形成式I化合物或其酸加成盐、式II化合物及其从甘露醇中的制备方法。
