90 mg 1-(2-(3,4,5-trimethoxyphenylethynyl)pyridin-3-yl)ethanone were suspended in 750 μL 1N sulfuric acid and 4 mg mercuric chloride and stirred for 1 h 45 minutes at 60° C. Then 2 mL of NaOH was added and the mixture stirred for additional 1 h at 25° C. Water was added and a neutral pH was adjusted with KHSO4 solution. The precipitate was filtered off and washed with water and dried to yield 80 mg 7-(3,4,5-trimethoxyphenyl)quinolin-5-ol 6.2 as solid. Analysis: HPLC-MS: Rt=1.18 min (method D), M+H=330.
