Abstract

A process for the preparation of new indán-1,3-dione derivatives of formula (I) or a pharmaceutically acceptable salt thereof **(See formula)** where R1, R2, R3 and R4 are each a hydrogen or halogen atom or an alkyl or alkoxy group or any two of the groups R1, R2, R3 and R4, taken together with the carbon atoms which are Bonds complete a substituted or unsubstituted carbocyclic ring and X represents a bond, provided that the groups R1, R2, R3 and R4 are not all hydrogen atoms; whose process is characterized in that, (a) it is reacted with acetonitrile in the presence of a base, a compound of formula (IX): **(See formula)** where R1, R2, R3 and R4 are as defined above and R5 and R6 are the same or different and each is an alkyl group; and (b), the thus formed compound of formula (I) is converted into a salt thereof.
