Procedure
[2-(4-{(2R)-2-[(tert-Butoxy)carbonylamino]-3-(4-chlorophenyl)propanoyl}piperazinyl)phenyl]-N,N-dimethylcarboxamide was prepared according to the procedure described in Preparation V by using N,N-dimethyl(2-piperazinylphenyl)carboxamide (Step 3) (260 mg, 1.1 mmol), Boc-p-Cl-D-Phe-OH (Peptech Corporation) (370 mg, 1.2 mmol), HOAT (Aldrich) (151 mg, 1.11 mmol), and EDC (Aldrich Chemical Company) (430 mg, 2.2 mmol). The compound was isolated as a crude white foam (480 mg) and used in the next step without further purification. MS (ESI, pos. ion) m/z: 515 (M+H). Calc'd for C27H35ClN4O4: 515.04.
