Procedure

10-Bromo-1,8-dihydroxy-9-anthrone (3.05 g) was dissolved in dichloromethane (100 ml) and ethanethiol (1 ml) was added. The solution was left stirring at room temperature for 6 hours, during which time the red-brown solution became yellow-green Removal of the solvent gave a yellow solid which, recrystallised from hexane, gave 1,8-dihydroxy-10-ethylthio-9-anthrone (2.63 g, 91%) as bright yellow needles, melting point 117°-118° C.
