実験手順
1-Chloro-N,N,2-trimethyl-prop-1-en-1-amine (0.08 0 mL, 0.60 mmol) was added to a solution of 3-[6-(azetidine-1-carbonyl)pyridin-3-yl]oxy-5-[(3S)-1-methyl-2-oxo-pyrrolidin-3-yl]oxy-benzoic acid (Intermediate 30) (202 mg, 0.49 mmol) in DCM (5 mL) and stirred at ambient temperature for 50 minutes. 2-Amino-pyrazine (CAS no. 5049-61-6) (94 mg, 0.98 mmol) and pyridine (0.80 mL, 0.98 mmol) were added and the reaction stirred for 16 hours. The solvent was removed under reduced pressure and the residue taken up in ethyl acetate (40 mL), washed with saturated sodium bicarbonate (20 mL), water (10 mL), and brine (10 mL), dried (MgSO4) and evaporated under reduced pressure to give the crude product. The residue was purified by chromatography on silica, eluting with a gradient of 0-4% methanol in DCM to give product (53 mg, 22%). 1H NMR δ300 MHz, CDCl3) 2.13-2.27 (m, 1H), 2.35 (quintet, 2H), 2.52-2.67 (m, 1H), 2.93 (s, 3H), 3.34-3.59 (m, 2H), 4.24 (t, 2H), 4.70 (t, 2H), 4.94 (t, 1H), 6.98 (s, 1H), 7.23 (s, 1H), 7.39 (d, 1H), 7.48 (s, 1H), 8.12 (d, 1H), 8.27 (q, 1H), 8.33 (d, 1H), 8.39 (d, 1H), 8.66 (s, 1H), 9.66 (s, 1H); m/z 489 (M+H)+.
