To 2.35 g (4.3 mmol) di-tert-butyl (4S)—N-(tert-butoxycarbonyl)-4-(4-nitrobenzyl)-L-glutamate in 50 mL methanol and under argon atmosphere palladium (10% on charcoal) was added and the suspension hydrogenated overnight at room temperature. The reaction mixture was filtered, the solvent evaporated and the residue was chromatographed on silica gel using a hexane/ethyl acetate gradient, and the appropriate fractions were combined and concentrated.
