Reaction Conditions

Reaction Steps

2-Aminothioxanthone (4.9 g.), anhydrous potassium carbonate (4.5 g.) and di(ethylene-glycol) diethyl ether (150 ml) were heated to reflux (180° C.) and 5.2 g. of 2-bromoethyl ether was added. The reaction was held at reflux for 24 hours, filtered hot and the solvent removed under vacuum. The residue was recrystallized from acetone to give 2-morpholinothioxanthone, mp 166-167° C. Structure was confirmed by IR, NMR, C-13 NMR and MS.
