Reaction Steps

Methyl thiosalicylate (6 g, 35.7 mM) and ethyl cyanoacetate (4 g, 35.4 mM) were dissolved in toluene (10 ml), and triethylamine (5 ml, 35.8 mM) was added to the solution, followed by heating for 7 hours under reflux. After the reaction solution was concentrated, ethanol was added to the residue. The mixture was allowed to stand, and the crystals precipitated were taken out by filtration to give crude crystals. The crude crystals were recrystallized from ethanol to give the title compound as needles (5.4 g, 60.7%).
