An Emrys process vial (2-5 ml) for microwave was charged with 4-chloro-6-(2,2,2-trifluoro-1-phenyl-ethoxy)-pyrimidine (30 mg, 0.1 μmol), 4-borono-L-phenylalanine (32 mg, 0.16 mmol), 1 ml of acetonitrile and 0.6 ml of water. Aqueous sodium carbonate (0.42 ml, 1M) was added to above solution followed by 10 mol percent of POPd2 (dihydrogen di-μ-chlorodichlorobis(di-tert-butylphosphinito-κP)dipalladate. The reaction vessel was sealed and heated to 120° C. for 30 minutes by microwave. After cooling, the reaction mixture was evaporated to dryness. The residue was dissolved in 2.5 ml of methanol, and the product was purified with Prep-LC to give 4.8 mg of 2-amino-3-{4-[6-(2,2,2-trifluoro-1phenyl-ethoxy)-pyrimidin-4-yl]-phenyl}-propionic acid, yield 11%. 1H-NMR (400 MHz, CD3OD): δ 3.20 (m, 1H), 3.40 (m, 1H), 4.25 (t, 1H), 6.82 (dd, 1H), 7.43 (m, 5H), 7.57 (s, 1H), 7.60 (m, 2H), 8.10 (d, 2H), 8.75 (s, 1H).
