Reaction Steps

tert-Butyl 3-[N-((1R)-2-{4-[2-(N,N-dimethylcarbamoyl)-phenyl]piperazinyl}-1-[(4-chlorophenyl)methyl]-2-oxoethyl)carbamoyl](3S)-1,2,3,4-tetrahydro-isoquinoline-2-carboxylate was prepared according to the procedure described in Preparation V by using (2-{4-[(2R)-2-amino-3-(4-chlorophenyl)-propanoyl]-piperazinyl}phenyl)-N,N-dimethylcarboxamide HCl salt (Step 5) (230 mg, 0.50 mmol), Boc-L-Tic-OH (Bachem Company) (150 mg, 0.55 mmol), HOAT (Aldrich) (68 mg, 0. 50 mmol), EDC (Aldrich) (190 mg, 1.00 mmol) and DIEA (Aldrich) (87 μL, 0.50 mmol). The compound was isolated and purified by column chromatography (CH2Cl2: 1.5% 2 M NH3 in MeOH). (255 mg). MS (ESI, pos. ion) m/z: 674 (M+H). Calc'd for C37H44ClN5O5: 674.23.
