Participants

Reaction Steps

To a solution of 5-(9-isopropyl-2-morpholin-4-yl-9H-purin-6-yl)-pyrimidin-2-ylamine, (1.03 g, 3.03 mmol) in 15 ml of chloroform, was added slowly NBS (594 mg, 3.34 mmol) at a temperature of 5° C. The reaction was continued for 2 h at this temperature. After simple work-up, the product 5-(8-bromo-9-isopropyl-2-morpholin-4-yl-9H-purin-6-yl)-pyrimidin-2-ylamine was purified by flash column (solvent system: 50% ethyl acetate in hexane) to deliver 5-(8-bromo-9-isopropyl-2-morpholin-4-yl-9H-purin-6-yl)-pyrimidin-2-ylamine in a yield of 52% (660 mg). 1H NMR, MeOD: 9.67 (s, 2H), 4.90 (m, 1H), 3.89 (m, 4H), 3.82 (s, 4H), 1.72 (d, 6H). m/z: 419.31, 421.07 [MH]+.
