Procedure

A solution of borane-tetrahydrofuran complex in tetrahydrofuran (1 M., 38 ml.) is added slowly to a solution of 3-chloro-5-methoxyxanthone (15 g.) in tetrahydrofuran (200 ml.). The mixture is refluxed for 2 hours, cooled to room temperature and poured into water. The precipitate is filtered, dried and recrystallised from methanol to give 3-chloro-5-methoxyxanthene, m.p. 106°-108° C.
