Reaction Conditions

Reaction Steps

An intimate mixture of 2-chloro-5-methoxythioxanth-9-one (8 g.) and aluminium isopropoxide (32 g.) is heated and stirred in an atmosphere of nitrogen for 31/2 hours at 190° C. The mixture is cooled, 2N-hydrochloric acid (210 ml.) is added and the mixture extracted three times with ether. The combined ether extracts are washed with brine, dried over MgSO4 and the solvent evaporated in vacuo to give 2-chloro-5-methoxythioxanthene, m.p. 95°-96° C. on recrystallisation from methanol.
