Reaktionsschritte

Triethylamine (0.18 mL, 1.29 mmol, 1.5 equiv.) was added to a solution of 5-(3-((cyclopropylamino)methyl)phenyl)-N-neopentylbenzo[d]isoxazol-3-amine (exemplary compound 51) (0.30 g, 0.86 mmol, 1 equiv.) in DCM (10 mL) and the mixture was subsequently cooled to −70° C. Benzoylchloride (0.12 mL, 1.03 mmol, 1.2 equiv.) was added in drops and the mixture was slowly heated to RT and stirred for 15 hours. The reaction mixture was diluted with DCM (80 mL) and extracted with sat. aq. sodium hydrogen carbonate sol. (1×15 mL) and sat. aq. NaCl solution (1×15 mL), dried (MgSO4) and the solvent removed in a vacuum. After column-chromatographic purification (EtOAc/hexane; 10:1), the desired product (0.30 g, 77%) is obtained.
