The invention relates to a process for obtaining 3,3- diphenylpropylamines of general formula (I), particularly Fesoterodine, as well as their enantiomers, solvates and salts, comprising a chemoselective reduction of the acid group against the ester group in compounds of general formula (V), wherein R1 is C1-C8 alkyl; and R3 and R4, independently of one another, represent H or C1-C8 alkyl, or together form a ring of 3 to 7 members with the nitrogen to which they are bound. The invention also relates to the compounds of formula (V), as well as their enantiomers, solvates and salts.
该发明涉及一种用于获得通式(I)所示的3,3-二苯基丙胺,特别是非索特罗定(Fesoterodine)的过程,以及它们的对映体、溶剂合物和盐,包括在通式(V)所示化合物中对酸基进行化学选择性还原以对抗酯基,其中R1为C1-C8烷基;R3和R4,彼此独立地,代表H或C1-C8烷基,或者一起与它们结合的氮形成一个由3到7个成员组成的环。该发明还涉及通式(V)所示的化合物,以及它们的对映体、溶剂合物和盐。
