Reaktionsschritte

To a solution of the amine 150 (334 mg, 0.85 mmol), 3-(2-methoxyphenylamino)-3-oxopropanoic acid (27) (355 mg, 1.70 mmol), 1-hydroxybenzotriazole (275 mg, 2.04 mmol) in dimethylformamide (8.5 mL) was added N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (391 mg, 2.04 mmol) and the reaction mixture was stirred at room temperature until completion of the reaction. The dimethylformamide was evaporated and the residue was quenched with a saturated solution of sodium bicarbonate. The aqueous layer was extracted three times with ethyl acetate. The combined organic layers were washed with water and brine, dried over anhydrous MgSO4, filtered and evaporated to afford title compound 146 as a white solid (180 mg, 36% yield). 1H NMR (DMSO-d6) 6 (Ppm): 10.59 (s, 1H), 9.64 (s, 1H), 8.52-8.50 (m, 1H), 8.08-8.06 (m, 2H), 7.88 (d, J=12.9 Hz, 1H), 7.78 (m, 2H), 7.51-7.38 (m, 4H), 7.07 (s, 2H), 6.92 (m, 1H), 6.65 (m, 1H), 3.86 (s, 3H), 3.65 (s, 2H), 3.48 (s, 2H), 2.18 (s, 6H). MS (m/z): 585.2 (M+H).
