A microwave vial was charged with 4-chloro-2-amino-6-[1-(4-methylphenyl)-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. Aqueous sodium carbonate (0.3 ml, 1N) was added to above solution followed by 5 mol percent of dichlorobis(triphenylphosphine)-palladium(II). The reaction vessel was sealed and heated to 150° C. for 5 minutes with microwave. After cooling, the reaction mixture was evaporated to dryness. The residue was dissolved in 2.5 ml of methanol, was then purified by Prep-LC to give 14.6 mg of 2-amino-3-(4-{2-amino-6-[2,2,2-trifluoro-1-(4-methylphenyl)-ethoxy]-pyrimidin-4-yl}-phenyl)-propionic acid. 1H NMR (300 MHz, CD3OD) δ 7.94 (d, J=8.20 Hz, 2H), 7.47 (d, J=7.24 Hz, 4 H), 7.27 (d, J=8.01 Hz, 2H) 6.80 (s, 1H), 6.75 (m, 1H), 4.30 (t, 1 H), 3.21-3.44 (m, 2 H), 2.37 (s, 3H).
