Although the amide group of N,N-diethyl-2,4-dimethoxybenzamide facilitates directed ortho-metallation and subsequent allylation of the aromatic ring, it is not readily hydrolyzed prior to conversion into the title isochromenone. This article describes the use of 1-(2-allyl-4,5-dimethoxybenzoyl)-4-methylpiperazine and N,N-diethyl-2-(2-hydroxypropyl)-4,6-dimethoxybenzamide as alternative substrates for conversion into 6,8-dimethoxy-3-methyl-3,4-dihydro-1H-isochromen- 1-one.
