Procedure

A solution of tert-butyl 2-(R)-{tert-butoxycarbonyl-[4-(4-chlorophenyl)piperazine-1sulfonyl]amino}-3-phenylpropionate (579 mg, 1.15 mmol), [prepared as described in Step 2 above], in methylene chloride (20 ml) was saturated with dry hydrogen chloride gas at 0° C. The reaction vessel was sealed and the reaction mixture was stirred at RT. After 72 h, the reaction mixture was vented with nitrogen and then concentrated in vacuo. The residue was treated with methylene chloride and the product was filtered to give 2-(R)-{[4-(4-chlorophenyl)piperazine-1-sulfonyl]amino}-3-phenylpropionic acid as a white solid (74%), mp 176.0-178.0 ° C.
