Procedure
2,3,3-Trimethyl-3H-indolium perchlorate (5 g.) and 4-p-methoxyphenylbut-3-ene-2-one (10 g.) were heated together on the steam bath for three hours. The cooled mixture was diluted with methanol and filtered. The product was purified by recrystallization from acetonitrile. Yield 4.1 g.; m.p. 298°-300° .
