実験手順
Add triphenylphosphine (5.24 g, 20.0 mmol) and diisopropylazodicarboxylate (4.04 g, 20.0 mmol) to a solution of 5-(3-(hydroxymethyl)phenylthio)nicotinonitrile (4.84 g, 20.0 mmol) and 1-(2,4-dihydroxy-3-methylphenyl)ethanone (3.32 g, 20.0 mmol) in THF (100 mL). Stir the reaction for 24 h. Quench the reaction with water and extract with EtOAc. Dry, filter and concentrate. Purify the residue by flash chromatography on silica gel eluting with a mixture of EtOAc and hexanes (15:85 to 20:80) to give an off-white solid. Recrystallize the solid from a mixture of EtOAc and hexanes to afford the title compound (3.94 g, 50%): 1H NMR (CDCl3) δ 2.14 (s, 3H), 2.57 (s, 3H), 5.18 (s, 2H), 6.44 (d, J=9.0 Hz, 1H), 7.46-7.49 (m, 3H), 7.52 (s, 1H), 7.59 (d, J=9.0 Hz, 1H), 7.62-7.63 (m, 1H), 8.63-8.64 (m, 2H), 12.78 (s, 1H).
