실험 절차

tert-Butyl 2-(2-cyano-4-pyridyl)ethylcarbamate (3.0 g, 12 mmol) and methyl thiosalicylate (3.6 g, 21 mmol) were dissolved in toluene (12 ml), and triethylamine (6.0 ml, 43 mmol) was added thereto. The mixture was refluxed for 8 hrs. The solvent was evaporated, and the residue was subjected to a silica gel column chromatography. The fractions eluted with ethyl acetate-hexane (2:1, v/v) were collected, concentrated and recrystallized from hexane-ethanol to give the titled compound (3.3 g, 71%) as white crystals.
