Process for the preparation of chiral, nonracemic (4-aryl-2,5-dioxoimidazo- lidin- 1-yl)acetic acids The present invention relates to a process for the preparation of chiral, nonracemic compounds of the formula I in which R1 and R2 have the meanings indicated in claim 1 and which are useful intermediates for the preparation of pharmaceutical active compounds in which, for resolution, a salt is formed from the racemic compound of the formula I and a chiral, nonracemic amino compound. It furthermore relates to compounds of the formula I and esters thereof. |
