Cesium carbonate → 5-bromo-1-(2-(methylsulfonyl)ethyl)-3-morpholinopyridin-2(1H)-one

Participants

Reaction Steps

Method 1 was followed using 5-bromo-3-morpholinopyridin-2(1H)-one (1.0 equiv.), (methylsulfonyl)ethene (1.2 equiv.) and cesium carbonate (1.2 equiv.) at room temperature to give 5-bromo-1-(2-(methylsulfonyl)ethyl)-3-morpholinopyridin-2(1H)-one in 98% yield. 1H NMR (400 MHz, <cdcl3>) δ ppm 2.92 (s, 3H) 3.09-3.23 (m, 4H) 3.53 (t, J=6.65 Hz, 2H) 3.78-3.96 (m, 4H) 4.32 (t, J=6.65 Hz, 2H) 6.69 (s, 1H) 7.23 (d, J=2.35 Hz, 1H). LCMS (m/z) (M+H)=365.1/366.9, Rt=0.57 min.
