Versuchsvorschrift

An Emrys process vial (2-5 ml) for microwave was charged with (6-chloro-pyrimidin-4-yl)-(3-cyclopentyloxy-4-methoxy-benzyl)-amine (64 mg, 0.19 mmol), 4-borono-L-phenylalanine (40 mg, 0.19 mmol) and 2 ml of acetonitrile. Aqueous sodium carbonate (2 ml, 1M) 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 and purified with Prep-LC to give 5.3 mg of 2-amino-3-{4-[6-(3-cyclopentyloxy-4-methoxy-benzylamino)-pyrimidin-4-yl]-phenyl}-propionic acid, yield 6%. 1H-NMR (400 MHz, DMSO-d6): δ 1.46 (m, 2H), 1.62 (m, 4H), 3.01 (m, 2H), 3.08 (m, 2H), 3.65 (s, 3H), 4.20 (m, 1H), 4.46 (d, 2H), 4.68 (m, 1H), 6.82 (t, 2H), 6.87 (d, 2H), 7.40 (d, 2H), 7.90 (s, 2H), 8.25 (s, 2H), 8.6 (s, 1H).
