4-Methylmorpholine → HCID 178462204, compound

Participants

Reaction Steps

A mixture of trans-4-(2-amino-5-fluorophenylamino)cyclohexanecarbonitrile (195 mg, 0.83 mmol), (S)-2-tertbutoxycarbonylaminopropionic acid (174 mg, 0.92 mmol), HOAt (125 mg, 0.92 mmol), 4-methylmorpholine (0.20 mL, 1.83 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (192 mg, 1.0 mmol) in THF (3 mL) was stirred at RT for 18 h under a nitrogen atmosphere. The reaction mixture was partitioned between EtOAc and water. The organic fraction was washed with brine, dried (MgSO4), concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-50% EtOAc in cyclohexane) to afford the title compound as a white foam (199 mg, 60%). LCMS (Method B): RT 3.37 [M+H]+ 405.2
