Isocyanate → Methyl 3-{[(N-Methylcarbamoyl)methylthio]methyl}-4-oxo-4-(3-pyridyl)butanoate

Participants

Reaction Steps

A solution of methyl 3-(3-pyridylcarbonyl)but-3-enoate in dichloromethane (0.5 mL, 0.1 mM), triethylamine in dichloromethane (0.5 mL, 0.1 mM) and N-methyl-2-sulfanylacetamide (0.6 mL, 0.12 mmol) was stirred for 24 h. PS isocyanate resin (60 mg) was added to the reaction mixture and stirred for 24 h. The solution was filtered and concentrated to give the title compound in quantitative yield, ESMS, (M+1)+311.
