Reaction Steps

(2S)-2-(2-Methoxybenzoylamino)-3-methylpentanoic acid tertbutyl ester (341 mg, 1.06 mmol) was dissolved in trifluoroacetic acid/CH2Cl2 (1:1, 10 ml). After 2 h at room temperature the solvent was removed in vacuo and the residue was purified by flash chromatography (eluant: 1% acetic acid, 2% methanol, 97% chloroform) to give a colourless oil identified as the title compound (242 mg, 0.91 mmol, 86%).
