treated with diazomethane, methyl iodide, dimethyl sulfate, and diethyl sulfate to give 1- and 2-alkylated compounds. The 1,8-dihydrocycloheptapyrazol-8-one (2a) also reacted with 2-(dimethylamino)ethyl, 2-(diethylamino)ethyl, 3-(dimethylamino)propyl, and 2,3-dihydroxypropyl chloride to afford the corresponding 1-substituted products. A preliminary study was made of the biological activities of some of
