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 microwave irradiation 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 hexane to give the title compound (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).
