Procedure

To a solution of N-isoamyl-N-(3 Methoxyphenylsulfonyl)D-tert-leucine benzyl ester (2.0 g, 4.33 mmol) in MeOH (12 ml) is added 10% palladium on carbon (200 mg) and the reaction is stirred under ambient pressure of hydrogen for 4 hours. The reaction is filtered through celite and concentrated affording the title compound (1.6 g, 99%).
