Br and Br; comprising the steps of:
(i) reacting a compound of formula (II),
wherein OX represents hydroxy or O
−
M
+
, in which M
+
is a cation selected from Li

, Na
+
and K
+
, and
Y is as defined above;
with trans-cinnamaldehyde (III),
in the presence of a secondary amine compound; then
(ii) treating the product of the preceding step with acid to afford the compound of formula (I).
The above process may also be used in the production of tolterodine and fesoterodine, which are useful in the treatment of overactive bladder.
本发明提供了一种制备式(I)化合物的方法,其中Y选自CH3,CH2OH,CH2CH2OH,CH2Br和Br组成的群体,包括以下步骤:(i)反应式(II)化合物,其中OX代表羟基或O-M +,其中M +是从Li +,Na +和K +中选择的阳离子,而Y如上所述;与反-肉桂醛(III)在次胺化合物的存在下;然后(ii)用酸处理前述步骤的产物以得到式(I)化合物。上述方法也可用于生产对治疗过度活跃膀胱有用的托特罗啶和费索托罗定。
