Procedure

(3S)-3-[(1-Methylindole-2-carbonyl)valinyl] amino-4-oxobutanoic acid, t-butyl ester semicarbazone (170 mg, 0.36 mmol) was dissolved in anisole (0.2 mL) and methylene chloride (2 mL) and the resulting solution was treated with TFA (1 mL). The resulting solution was stirred for 3.5 hours under a nitrogen atmosphere at room temperature. The reaction mixture was concentrated in vacuo and chased with methylene chloride to give a purple foam. Trituration of the foam with ether afforded the title product as a solid purple powder (133 mg, 89%).
