Participants

Reaction Steps

6-Bromophthalazinone (11.2 gm, 0.05 mole) was slurried in 80 ml dimethylsulfoxide. To this was added 22 ml 45% KOH (0.25 mole). After stirring 10 minutes 16 gm 2-(diisopropylamino)ethyl chloride hydrochloride was added and the mixture stirred for 18 hours. A water bath was used to moderate the slightly exothermic reaction (temperature <=25°). Water (100 ml) was added to the reaction mixture, which was then stirred another hour.
