Abstract

A process for preparing a phthalazone derivative represented by general formula i ** (see formula) ** Characterized in that a compound of the general formula ii is reacted ** (see formula) ** Where r is an acyl group, with isobutylene in the presence of a catalyst, and the product obtained from the general formula iii is then hydrolysed ** (see formula) ** Where r is as defined above, to obtain the compound of formula i.
