N-(4-(2-chloropyrimidin-4-yl)phenyl)methanesulfonamide (750 mg 2.64 mmol) and potassium carbonate (730 mg, 2 eq.) were placed in a round bottomed flask and suspended in acetone (50 mL). The mixture was stirred for several minutes before adding bromoacetonitrile (368 μL, 2 eq.). The reaction mixture was stirred at room temperature for 48 h. The crude reaction mixture was concentrated in vacuo and the residue taken up in ethyl acetate (200 mL) and washed with water (2×100 mL), brine (100 mL) and then dried (sodium sulfate). The organic phase was concentrated in vacuo to give N-(4-(2-chloropyrimidin-4-yl)phenyl)-N-(cyanomethyl)methanesulfonamide (762 mg, 89% yield) as a fawn solid. 1H NMR (300 MHz, d6-DMSO) δ 8.86 (1H, d, J=5.0 Hz); 8.28 (2H, d, J=8.7 Hz); 8.18 (1H, d, J=5.5 Hz); 7.66 (2H, d, J=8.7 Hz); 4.97 (2H, s); 3.22 (3H, s). LC-ESI-MS (method B): rt 5.9 min.; m/z 323.2/325.2 [M+H]+.
