Reaction Steps
A mixture of (R)-tert-butyl 1-amino-3-(4-iodophenyl)-1-oxopropan-2-ylcarbamate (370 mg, 0.948 mmol), imidazole (85 mg, 1.25 mmol), 8-hydroxyquinoline (30 mg, 0.206 mmol), K2CO3 (150 mg, 1.08 mmol) and CuI (20 mg, 0.105 mmol) in DMSO (4 mL) was degassed with argon, then was stirred at 130 C for 18 h. The mixture was purified by HPLC to give (R)-tert-butyl 3-(4-(1H-imidazol-1-yl)phenyl)-1-amino-1-oxopropan-2-ylcarbamate (250 mg).
