3,3-diphenylpropylamines of general formula (I), particularly Fesoterodine, as well as their enantiomers, solvates and salts, can be produced by treating a compound of formula (II) with a chiral alcohol to yield the diastereomeric esters of formula (IV) and (IV′), which can be further transformed into a compound of formula (I), or an enantiomer, solvate or salt thereof, wherein R1 is C1-C8 alkyl; and R2 and R3, independently of one another, represent H or C1-C6 alkyl, or together form a ring of 3 to 7 members with the nitrogen to which they are bound.
一般式(I)的3,3-二苯基丙基胺,特别是费索特罗定(Fesoterodine),以及它们的对映体、溶剂合物和盐类,可以通过用手性醇处理一种具有式(II)的化合物来生产,以得到式(IV)和(IV')的对映异构酯,然后可以进一步转化为具有式(I)的化合物,或其对映体、溶剂合物或盐类,其中R1为C1-C8烷基;R2和R3分别表示H或C1-C6烷基,或者一起形成一个由3到7个成员组成的环,与它们结合的氮原子。
