Procedure

To a solution of 5-(8-bromo-9-isopropyl-2-morpholin-4-yl-9H-purin-6-yl)-pyrimidin-2-ylamine, (30 mg, 0.072 mmol) and Pd(dppf)Cl2, (3 mg, 5% mmol) in 3 ml of anhydrous dioxane, was added slowly dimethyl zinc (210 μl, 1.0 M in heptane solution) in a sealed tube. The mixture was heated to about 65° C. MeOH was added drop wise and the solvents removed in vacuo. EtOAc was added to the residue and the resulting solution washed with 1 M HCl, water, brine and then dried over Na2SO4. The solvent was removed and the crude mixture was subjected to flash chromatography on silica gel to obtain 5-(9-isopropyl-8-methyl-2-morpholin-4-yl-9H-purin-6-yl)-pyrimidin-2-ylamine 8 mg in a yield of 47%. 1H NMR, MeOD: 9.40 (s, 2H), 4.81 (m, 1H), 3.89 (m, 4H), 3.82 (s, 4H), 3.71 (s, 3H), 1.73 (d, 6H). m/z: 355.16 [MH]+.
