Abstract
Abstract The new pyrazolo [4, 3-c] quinolin-3-one derivatives 3a-c and 6a-c were prepared by the following three steps: first the preparation of ethyl 4-hydroxyquinoline-3-carboxylate derivatives 1 and 4 by reaction of isatoic anhydrides and ethyl malonate and ethyl acetoacetate respectively, then chloration of 1 and 4 with phosphorus oxychloride to give 2 and 5 and finally the condensation of 2 and 5 with hydrazine and its derivatives.
