실험 절차

To a solution of 3-[5-bromo-4-(4-methoxy-phenyl)-thiazol-2-ylmethoxy]-2,6-difluoro-benzamide (0.1 g, 0.02 mmol) in DMF:H2O (2:1), 3-pyridine boronic acid (0.054 g, 0.04 mmol), potassium phosphate (0.056 g, 0.025 mmol) was added. The reaction mixture was degassed for 10 min and then dichlorobis [(triphenylphosphine)-Palladium (II) (0.023 g, 0.003 mmol) was added and again degassed for 10 min. The reaction mixture was heated at 120° C. for 12 h under the nitrogen atmosphere. DMF was distilled off, after cooling to r.t., water was added into reaction mixture and extracted with ethyl acetate, The combined organic layers were dried over anhydrous Na2SO4, and evaporated to dryness under reduced pressure. The compound was purified by chromatography on silica (230-400μ) using ethyl acetate/hexane (50:50) as the eluent to provide the title compound as yellow solid (0.050 g, 50%). 1H NMR (DMSO-d6, 400 MHz): δ 3.75 (s, 3H), 5.59 (s, 2H), 6.92 (d, 2H, J=8.8 Hz (o-coupling), 7.14 (dt, 1H, J=9.2 Hz (o-coupling), 7.36 (d, 2H, J=8.4 Hz (o-coupling), 7.45 (dt, 2H, J=9.2 Hz (o-coupling) J=5.2 Hz (o-coupling), 7.79 (m, 1H), 7.88 (broad s, 1H), 8.16 (broad s, 1H), 8.53 (d, 1H, J=2.0 Hz (m-coupling), 8.57 (d, 1H, J=4.8 Hz). MS ES+ (454.10), HPLC (method 5) Rt=15.26 min.
