The combined extracts were washed with brine, dried over Na2SO4, and concentrated in vaccuo to provide the crude product. Purification by silica gel chromatography provided (2-chloro-4-methoxyphenyl)(4-chlorophenyl)methanone(1.1 g, 4.1 mmol). (2-Chloro-4-methoxyphenyl)(4-chlorophenyl)methanone was dissolved in AcOH (60 mL) and 49% HBr (60 mL) was added. After 12h at 90° C. all volatiles were evaporated in vaccuo to afford (4-chlorophenyl)(2,4-dihydroxyphenyl)methanone in quantitative yield. This was dissolved in MeOH (30 mL) and THF (6 mL) and cooled to 0° C. Into the reaction mixture NaBH4 (235.5 mg, 6.2 mmol) was added. After 30 minutes the reaction was quenched with aq. NH4Cl and extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4, and concentrated in vaccuo.
