Manufacturing synthesis of 5-substituted phthalides

A manufacturing synthesis of 5-chlorophthalide has been elaborated. The key step of the procedure is ortho-lithiation of 4-chloro-N,N-diisopropylbenzamide, followed by formylation with dimethyl formamide. Reduction of the formyl moiety and subsequent ring
