Participants

Reaction Steps

Add 1N NaOH (107 mL) to the product of Step A (14.80 g) in THF (100 mL) and stir overnight. Concentrate the THF solution in vacuo and partition between EtOAc (700 mL)/2N HCl (200 mL). Concentrate the dried (MgSO4) EtOAc solution in vacuo to a residue. Add CH2Cl2 (50 mL) and concentrate in vacuo (3 times) to give N-benzyloxycarbonyl-3-methanesulfonamido-D,L-phenylalanine.
