摘要：
The present invention relates to a process for preparing compounds of the general formula (I) in which m, n, o, R
1 , R
2 and R
3 are each defined as mentioned below, the enantiomers thereof and the diastereomers thereof, which are particularly suitable for preparing compounds of the general formula (II) in which m, o, R
1 , R
2 , R
3 and R
4 are each defined as mentioned below. The compounds of the general formula (II) possess B1-antagonistic properties.
