Reaction Steps

To a solution of 4-aminoresorcinol (1 eq) and ethylxanthic acid (3 eq) in ethanol was added potassium hydroxide (2.1 eq). The mixture was refluxed for two hours then diluted with water and acidified using 1N HCl to a pH of 4. The product was extracted into ethyl acetate then concentrated. The resulting solid was triturated with dichloromethane to give pure product with a 90% yield. MH+=168.1.
