Abstract:
The present invention relates to a novel method for preparing (4R)-4-(4-cyano-2-methoxyphenyl)-5-ethoxy-2,8-dimethyl-1,4-dihydro-1,6-naphthyridine-3-carboxamide of the formula 4R (I) and the metabolites of (4S)- and (4R)-4-(4-cyano-2-methoxyphenyl)-5-ethoxy-2,8-dimethyl-1,4-dihydro-1,6-naphthyridine-3-carboxamide of the formula (I), the formulae M1a (S), M1b (R), M2a (S), M2b (R), M3a (S) and M3b (R) and use thereof.

Claim (Index 2):
A method for preparing compounds of the formulae M1a (S) and M1b (R) comprising preparing a compound of the formula rac M1 by oxidizing a compound of the formula rac (I) and separating the racemate of formula rac M1 into enantiomers of the formulae M1a (S) and M1b (R) by chromatographic methods on a chiral phase.
