Reaction Steps

To a mixture of morpholine (0.78 mL, 8.98 mmol) and potassium carbonate (3.7 g, 26.9 mmol) in acetonitrile (10 mL) was added propargyl bromide (1.0 mL, 8.98 mmol) and the mixture was heated to about 80 C overnight. The reaction was quenched by addition of water and the mixture was extracted with diethyl ether. The combined organic extracts were washed with water, dried (Na2SO4), filtered and concentrated under vacuum to provide Example 639. 1H NMR (300 MHz, CD3OD) δ 2.57 (m, 4H) 2.68 (t, J=2.4 Hz, 1H) 3.29 (s, 2H) 3.70 (m, 4H).
