Participants

Reaction Steps

Morpholine (510 mg, 5.86 mmol) and 4-nitrophenyl prop-2-yn-1-ylcarbamate (800 mg (80% purity), 2.91 mmol) in dichloromethane (10 ml) were stirred at room temperature for 4 hours and then the reaction solution was purified directly by chromatography on silica using ethyl acetate as eluent to give N-prop-2-yn-1-ylmorpholine-4-carboxamide (453 mg, 92%) as a pale yellow solid; NMR Spectrum: (CDCl3) 2.24 (t, 1H), 3.37 (m, 4H), 3.69 (m, 4H), 4.05 (m, 2H), 4.65 (s, 1H).
