To a solution of bis-(5-chloro-2-hydroxyphenyl)-methane (24.4 g, 90.7 mmol) in dry DMF (340 mL) was added diiodomethane (25.5 g, 95.0 mmol) and potassium carbonate (18.2 g, 132 mmol).The mixture was stirred at 105° C. for 16 h. The mixture was added to ice water (1200 mL) and stirred for 30 min. The product was isolated by filtration, and washed with water and suspended in a mixture of ethanol (200 mL) and 4N NaOH (50 mL). The mixture was heated at 80° C. for 1 h. The mixture was added to water (600 mL) and 21.45 g (84%) 2,10-dichloro-12H-dibenzo[d,g][1,3]-dioxocin was isolated by filtration.
