실험 절차

A solution of (6-chloro-2-methoxy-pyrimidin-4-yl)-[2-(2-fluoro-4-trifluoromethyl-phenyl)-ethyl]-amine (493 mg, 1.408 mmol) and 3-carboxymethyl-1H-indol-5-yl boronic acid (370 mg, 1.689 mmol) in toluene (9 mL), EtOH (4.5 mL) and water (1 mL) is added Cs2CO3 (1.146 g, 3.52 mmol) and degassed with nitrogen for 5 minutes before addition of tetrakis(triphenylphosphine)palladium (0) (81.3 mg, 5 mol %). The reaction vessel is sealed and heated under microwave to 130° C. for 15 minutes. To the reaction mixture is added 1N hydrochloric acid to adjust pH to about 2. This mixture is extracted three times with EtOAc (40 mL). The combined, extracts are washed with brine, dried over sodium sulfate and concentrated. The residue is subjected to silica gel chromatography to give (5-{6-[2-(2-fluoro-4-trifluoromethyl-phenyl)-ethylamino]-2-methoxy-pyrimidin-4-yl}-1H-indol-3-yl)-acetic acid [116 mg, 17%, Example 52] as a solid. LC/MS: RT=2.57 minutes, MS: 489 (M+H). 1H NMR [300 MHz, (CD3)2SO]: □12.18 (1H, s), 11.05 (1H, s), 8.18 (1H, s), 7.24-7.76 (7H, m), 6.6 (1H, s), 3.87 (3H, s), 3.7 (2H, s), 3.6 (2H, m), 3 (2H, m). IC50=0.4 nM
