Reaction Steps

A solution of 4-ethoxythioxanth-9-one (4.4 g.) in n-butanol (100 ml.) is heated under reflux and sodium (6.0 g.) is added in portions to the boiling solution. Heating is continued until all the sodium has reacted, and the solvent is then removed by evaporation in vacuo. The residue is slurried with water, extracted with ether (3 × 50 ml.), the extracts dried and evaporated to give 4-ethoxythioxanthene, m.p. 95°-98° C. on recrystallisation from ethanol.
