실험 절차

1-Chloro-N,N,2-trimethyl-1-propenylamine (0.133 mL, 1.0 mmol) was added to a suspension of 3-{[6-(azetidin-1-ylcarbonyl)pyridin-3-yl]oxy}-5-[(3S)-tetrahydrofuran-3-yloxy]benzoic acid (350 mg, 0.94 mmol) in DCM (10 mL) and stirred at RT for 30 min. 2-Amino-5-methylpyrazine (196 mg, 1.82 mmol) and pyridine (0.148 mL, 1.82 mmol) were added and the reaction stirred at RT for 2 hours. The solvent was removed in vacuo and water (30 mL) added. The mixture was extracted with ethyl acetate (3×20 mL), washed with 2N hydrochloric acid (20 mL), water (10 mL), saturated aqueous sodium bicarbonate solution (20 mL), water (10 mL) and brine (20 mL). The combined organic extracts were dried (MgSO4), filtered and evaporated in vacuo. The residue was purified by chromatography, eluting with 0-10% methanol in DCM, to give the desired product as a colourless oil (150 mg). 1H NMR δ (CDCl3): 2.12-2.18 (1H, m), 2.22-2.29 (1H, m), 2.31-2.40 (2H, m), 2.56 (3H, s), 3.89-4.03 (4H, m), 4.25 (2H, t), 4.71 (2H, t), 4.97-5.00 (1H, m), 6.76 (1H, t), 7.15 (1H, t), 7.25 (1H, d), 7.38-7.40 (1H, m), 8.12 (1H, s), 8.14 (1H, d), 8.32 (1H, s), 8.34 (1H, d), 9.52 (1H, d); m/z 476 (M+H)+, 474 (M−H)−
