In another known process for the preparation of CVL there are three steps. The first step comprises the interaction of the methyl ester of 2-formyl-5-dimethylaminobenzoic acid with two equivalents of N,N-dimethylaniline to obtain the methyl ester of 2-[bis(4-dimethylaminophenyl)methyl]-5-dimethylaminobenzoic acid. After isolation, this benzoic acid is oxidized in the second step and finally in the third step the oxidized product is saponified and the lactone ring is closed to obtain the 3,3-bis(4-dimethylaminophenyl)-6-dimethylaminophthalide (CVL).
