p-Toluenesulfonic acid monohydrate → HCID 15908403, compound

Participants

Reaction Steps

A mixture of 1-[4-(methylsulfonyl)phenyl]pentene-1,4-dione (0.305 g, 1.2 mmol prepared according to the method of J. Med. Chem., 1997, 40 , 1619), 4-(2-furyl)aniline (0.35 g, 2 mmol), and p-toluenesulfonic acid monohydrate (0.015 g) in toluene (40 mL) was heated at reflux temperature for 16 hours using Dean-Stark apparatus. After cooling, volatiles were removed by evaporation. The residue was purified by flash chromatography eluting with hexane/ethyl acetate (4/1). The resulting solid was recrystallized from CH2Cl2/hexane to give the title compound (0.11 g, 24.3% yield).
