Dissolve [2-(2,4-difluoro-phenyl)-6-hydroxy-naphthalen-1-yl]-[4-(2-piperidin-1-yl-ethoxy)-phenyl]-methanone (540 mg, 1.11 mmoles), and methane sulfonyl chloride (254 mg, 2.22 mmoles) in 10 ml acetonitrile and add triethylamine (224 mg, 2.22 mmoles). Stir the mixture for 5 days at room temp. Add equivalent amounts of the sulfonyl chloride and triethylamine and stir for 30 minutes. Evaporate the mixture to dryness, dissolve in methanol and pass through an SCX column. Wash the column with methanol and elute the product with 2 N ammonia/methanol to yield 433 mg (69%) of the title compound: mass spectrum (ion spray) m/z=566 (M+H).
