Participants

Reaction Steps

To 5.0 g (0.017 mol) of 3-cyano-7-methoxythioxanthen-9-one 10,10-dioxide was added ethylenediamine, 10.8 g (0.18 mol), and sodium methoxide, (0.098 g, 0.002 mol), in methanol, 70 ml, and the mixture was refluxed for 70.5 hr. The mixture was then poured into ice water, 400 ml, and the precipitate was filtered and washed with water then was recrystallized from ethanol, DMSO and H2O to provide 1.1 g of 6-(2-imidazolin-2-yl)-2-methoxythioxanthen-9-one-10,10-dioxide with m.p. 220°-224° C.; TLC on silica gel (ethanol), Rf =0.44.
