実験手順

6-[(1,3-Dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]-2-pyridinecarbonitrile (1.25 g, 4.7 mmol) and methyl thiosalicylate (1.59 g, 9.4 mmol) were dissolved in toluene (10 ml), and triethylamine (5.0 ml, 35.8 mmol) was added thereto. The reaction mixture was refluxed for 15 hrs. After cooling, the precipitates were collected by filtration and recrystallized from hexane-chloroform to give the titled compound (1.48 g, 78%) as white crystals.
