Versuchsvorschrift

To a solution of 1,2,3,4-Tetrahydro-isoquinoline-3(S)-carboxylic acid {2-[3-(4-cyanobenzyl)-3H-imidazol-4-yl]-ethyl}-amide hydrochloride (Example 1, Step C) (0.23 g, 0.52 mmol) in DMF (5 mL) was added l-hydroxybenzotriazole (0.079 g, 0.52 mmol), EDC (0.099 g, 0.52 mmol), 2,3-dimethylbenzoic acid (0.077 g, 0.52 mmol) and N-methylmorpholine (0.23 mL, 2.08 mmol). After stiffing for 18 hr. the mixture was evaporated in vacuo and the residue was partitioned betweem EtOAc (50 mL) and saturated NaHCO3 solution (30 mL). The organic layer was washed with saturated NaCl solution (30 mL) and dried (MgSO4). Filtration and concentration gave the title compound after purification by preparative HPLC on a Delta-pak C-18 column eluting with 0.1%TFA/H2O: 0.1%TFA/CH4CN, 95:5 to 5:95.
