실험 절차

1-Chloro-N,N,2-trimethyl-prop-1-en-1-amine (0.14 mL, 1.1 mmol) was added to a solution of 3-[5-(dimethylcarbamoyl)pyrazin-2-yl]oxy-5-[(3S)-1-methyl-2-oxo-pyrrolidin-3-yl]oxy-benzoic acid (Intermediate 45) (358 mg, 0.9 mmol) in DCM (7 mL) and stirred at ambient temperature for 30 minutes. 4-Methyl-1,3-thiazol-2-amine (CAS no. 1603-91-4) (206 mg, 1.8 mmol) and pyridine (0.15 mL, 1.8 mmol) were added and the reaction stirred for 20 hours. The solvent was removed under reduced pressure. The residue was dissolved in ethyl acetate (30 mL), washed with water (2×10 mL) and brine (10 mL), dried (MgSO4) and evaporated. The residue was purified by flash chromatography on silica eluting with a gradient of 0 to 5% methanol in DCM to afford the product (200 mg, 45%). 1H NMR δ (300 MHz, CDCl3) 2.09-2.22 (m, 1H), 2.25 (s, 3H), 2.50-2.65 (m, 1H), 2.93 (s, 3H), 3.18 (d, 6H), 3.34-3.55 (m, 2H), 4.86 (t, 1H), 6.56 (s, 1H), 7.16 (s, 1H), 7.37 (s, 1H), 7.54 (s, 1H), 8.37 (s, 1H), 8.51 (s, 1H), 10.0-11.0 (br s, 1H); m/z 497 (M+H+).
