Reaction Steps

In a microwave vial, 4-chloro-2-amino-6-[1-(2-trifluoromethylphenyl)-2,2,2-trifluoro-ethoxy]-pyrimidine (33 mg, 0.1 mmol), 4-borono-L-phenylalanine (31 mg, 0.15 mmol) and 1 ml of acetonitrile, 0.7 ml of water. 0.3 ml of 1N aqueous sodium carbonate was added to above solution followed by 5 mole percent of dichlorobis(triphenylphosphine)-palladium(II). The reaction vessel was sealed and heated at 150° C. for 5 minutes with microwave irradiation. After cooling, the reaction mixture was evaporated to dryness. The residue was dissolved in 2.5 ml of methanol, and then was purified by Prep-LC to give 5.6 mg of 2-amino-3-(4-{2-amino-6-[2,2,2-trifluoro-1-(2-trifluoromethylphenyl)-ethoxy]-pyrimidin-4-yl}-phenyl)-propionic acid. 1H NMR (400 MHz, CD3OD) δ 7.96 (m, 3H), 7.80 (d, J=8.06 Hz, 1H), 7.74 (t, J=7.91 Hz 1H), 7.63 (t, J=8.06 Hz, 1H), 7.41 (d, J=8.3 Hz, 2H), 7.21 (m, 1H), 6.69 (s, 1H), 3.87 (m, 1H), 3.34 (m, 1H), 3.08 (m, 1H).
