Versuchsvorschrift
A mixture of methyl thiosalicylate (0.56 g, 3.4 mmol), 2-cyano-6-methoxypyridine (0.45 g, 3.4 mmol), triethylamine (0.70 ml, 5.0 mmol) and toluene (50 ml) was refluxed for 48 hrs as described in Example 1. The reaction mixture was concentrated under reduced pressure and recrystallized from ethanol to give the titled compound (0.12 g, 13%) as crystals.
