Procedure

A mixture of 2.3 g (0.055 mole) of 50% sodium hydride in mineral oil, 50 ml of dimethylformamide (DMF) and 10.0 g (0.05 mole) of thiopyrano [3,2-b]indol-4(5H)-one is stirred for 3 hours, then 12.2 g (0.1 mole) of dimethylaminopropylchloride is added. Stirring is continued for 20 hours at 95°, then the mixture is poured onto ice containing conc. HCl. The cloudy solution is clarified with charcoal, made basic with 20% sodium hydroxide solution, and the precipitated oil extracted with ether. The ether is dried, and dry HCl passed in. The precipitated salt weighed 10.1 g and is recrystallized from isopropanol, mp 226°-228° C.
