실험 절차

A solution of N-[(1-methylindole-2-carbonyl)valinyl]-3-amino-4-oxo-5-fluoropentanoic acid, t-butyl ester (19 mg, 0.041 mmol) and anisole (0.1 mL) in CH2Cl2 (1 mL) was treated with trifluoroacetic acid (0.5 mL) at room temperature. After 30 min the reaction mixture was concentrated and chased with methylene chloride. The crude residue was triturated with diethyl ether and the solid filtered to afford the title compound as a light brown solid (12 mg, 72% yield).
