Versuchsvorschrift

A mixture of 4-fluoro-N2-phenylbenzene-1,2-diamine (614 mg, 3.04 mmol), (S)-4-benzyloxy-2-tertbutoxycarbonylaminobutyric acid (1.0 g, 3.3 mmol), HOAt (0.450 g, 3.3 mmol), 4-methylmorpholine (0.7 mL, 6.7 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.63 g, 3.3 mmol) in DCM (15 mL) was stirred at RT for 18 h. The reaction mixture was partitioned between DCM and a saturated aqueous solution of NaHCO3. The organic fraction was washed with brine, dried (MgSO4), concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-30% EtOAc in cyclohexane) to afford the title compound as a yellow oil (1.22 g, 82%). LCMS (Method J): RT 4.17 min [M+H]+ 494.1.
