The condensation of 3-amino-1-(2-fluorophenyl)-6-methoxyindolin-2-one (I) with acrylonitrile (II) by means of K2CO3 in DMSO gives the propionitrile derivative (III), which was submitted to optical resolution with (+)-dibenzoyl tartaric acid to yield enantiomer (IV). The condensation of (IV) with isoquinoline-3-carboxylic acid (V) by means of DEC and HOBt in DMF affords the carboxamide (VI), which is treated with HCl in methanol to provide the propionic ester (VII). Finally, this compound is hydrolyzed with NaOH in methanol/water to furnish the target sodium propionate derivative as a pure enantiomer.
