Versuchsvorschrift

Dissolve (4-bromo-2-fluoro-phenyl)-acetic acid (692 mg, 3.0 mmol) in THF (24 mL) and add 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (618 mg, 3.2 mmol), stir for 10 minutes. Dissolve (3-amino-5-trifluoromethyl-phenyl)-morpholin-4-yl-methanone (740 mg, excluding excess ammonium chloride) from previous step in DCM (24 mL) with Et3N (3.3 mL, 23 mmol). Add the activated acid to the amine mixture and stir at room temperature for overnight. Dilute the resulting suspension with EtOAc and wash with saturated NaHCO3 and aqueous saturated sodium chloride successively. Dry the organic layer (MgSO4), concentrate and purify by silica gel column chromatography (EtOAc/Hexane gradient) to obtain the title compound (15% yield). LCMS (ES), m/z 491 (M+1).
