100% | With aq. NH3 In isopropyl alcohol | Example 48 2-Amino-4-Chloropyrimidine To a solution of 4-chloro-2-methanesulfonylpyrimidine (5 g, 26 mmol) in i-PrOH (20 ml) 20percent aq. NH3 (20 ml) was added and the mixture stirred for 20 min. at room temperature. The mixture was extracted with CH2Cl2 four times and the organic solvent removed under vacuum. 2-Amino-4-chloropyrimidine (3.3 g, 100percent) was obtained as a white solid. 1H-NMR (CDCl3, 200 MHz) δ5.26 (br, 2H, NH2), 6.67 (d, J5.2, 1H, H5), 8.17 (d, J5.2, 1H, H6).
