Zusammenfassung:A process for preparing 2-acyl-3,4-dialkoxy-anilines is described. The 2-acyl-3,4-dialkoxyanilines are useful intermediates in the preparation of 5,6dialkoxy-4-alkyl-2(1H)-quinazolinones. The substituted quinazolinones are active as cardiotonic agents. The 2-acyl-3,4-dialkoxyanilines have the following formula: wherein R1, R2 and R3 are lower alkyl having 1-5 carbon atoms and R2 and R3 when taken together are methylenedioxy.
