Process for the preparation of the optical isomers of a 2-aminonaphthyridine derivative |
| abstract |
Process for the preparation of the dextrorotatory isomer of the product of formula (I) from the salt of the corresponding racemic product with (+) - ephedrine. Use of the dextrorotatory isomer thus obtained for the preparation of the dextrorotatory isomer of the product of formula (II). |
