Morpholine → 3-Morpholin-4-yl-2-(morpholin-4-ylcarbonothioyl)acrylonitrile

Participants

Reaction Steps

To a solution of 3-morpholin-4-yl-3-thioxopropanenitrile (0.1 g, 0.59 mmol) in triethylorthoformate (0.245 mL, 1.48 mmol) was added morpholine (0.064 mL, 0.73 mmol). The reaction mixture was subjected to MWI at 150° C. for 10 min. The reaction mixture was concentrated to small volume until the product precipitated. The precipitate was filtered off, washed with MeOH and isohexane to give 3-morpholin-4-yl-2-(morpholin-4-ylcarbonothioyl)acrylonitrile (0.13 g, 83%). LCMS: (AA) ES+ 268.2. 1H NMR (400 MHz, d6-DMSO) δ: 3.96 m, 4H) and 3.67-3.78 (m, 12H).
