실험 절차

In a hard walled glass tube, a solution of (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(2,4-dichloro-phenyl)-ethyl]-amine (250 mg, 0.75 mmol), 3-(hydroxymethyl)phenylboronic acid (137 mg, 0.9 mmol) and Na2CO3 (79.7 mg, 0.75 mmol) in acetonitrile/water (6 mL, 2:1) is degassed over nitrogen for 10 minutes. Tetrakis(triphenylphosphine)palladium (0) (43.5 mg, 0.04 mmol) is added and the tube is sealed and set in a microwave for 25 minutes at 130° C. The reaction is dilute with 25 mL of water and extracted twice with ethyl acetate. The combined organic extracts are washed with brine, dried over sodium sulfate, filtered and concentrate in reduced pressure. The residue is purified by chromatography (SiO2 packed column), eluted with EtOAc/DCM to afford (3-{6-[2-(2,4-dichloro-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-phenyl)-methanol [165 mg, Example 78 (a)]. LCMS: RT=2.24 minutes, MS: 405 (M+H); 1H NMR (300 MHz, CDCl3): □8.05 (1H, s), 7.95 (1H, b)), 7.48 (3H, b), 7.42 (1H, s), 7.2 (1H, s), 6.45 (1H, s), 4.95 (1H, b), 4.78 (2H, b), 4.05 (3H, s), 3.72 (2H, b), 3.1 (2H, t, J=3.5 Hz); and to afford (3′-chloro-4′-{2-[6-(3-hydroxymethyl-phenyl)-2-methoxy-pyrimidin-4-ylamino]-ethyl}-biphenyl-3-yl)-methanol [110 mg, Example 78(b)]. LCMS: RT=2.12 minutes, MS: 477 (M+H).
