Procedure

5-Ethyl-1,2-dihydro-3-methyl-4-phenyl-5H-pyrido[1',2':1,2]-imidazo[4,5-b]quinoxalinium perchlorate (3.1 g.) in 40 ml. of dimethyl sulfoxide is heated on a hot plate for 10 minutes. The dimethyl sulfoxide solution is poured into an excess of diethyl either and a green oil separates. The oil is crystallized from a chloroform-ether solution. Recrystallization from chloroform-ether affords 80% yield of product having a melting point of 262°-264° C.
