Abstract

"Process for obtaining carbostyril derivatives", of general formula ** (See formula) ** wherein R1 means one or more monovalent substituents, R2 means a cycloalkyl, aralkyl or aryl radical, optionally substituted on the ring, or an alkyl, alkoxyalkyl or alkylmercaptoalkyl radical, optionally substantially substituted, R3 means a carboxyalkyl radical , carbalkoxyalkyl, cyanoalkyl or cyano, and R4 means a hydrogen atom or an alkyl or acyl radical, characterized in that a compound of the general formula is reacted: ** (See formula) ** wherein R1, R2 and R4 have the meaning indicated above, with an acyl derivative of the general formula: X-CO-CH2-R3 wherein X means a halogen atom, an alkoxy radical or a hydroxyl radical and R3 has the meaning indicated above, and the compounds thus formed, of the general formula: ** (See formula) ** wherein R1, R2, R3 and R4 have the meaning indicated above, cyclize.
