Participants

Reaction Steps

In 20 ml CCl4 were combined 5.00 g 4,5,5a,6-tetrahydro-3H-isoxazolo[5,4,3-kl]acridine and 9 ml ethyl isocyanate. The mixture was refluxed for two days. After the first day, 9 ml more ethyl isocyanate was added. The reaction mixture was then cooled in ice and the precipitate filtered. The precipitate was recrystallized from 1:1 DCM/hexanes and dried in vacuo at 80° C. to yield 3.91 g crystals, m.p. 189° C.
