Versuchsvorschrift

The title compound was prepared from (2R)-1-(tert-butoxycarbonyl)piperidine-2-carboxylic acid (52 mg, 0.23 mmol), N-[5-chloro-2-(1H-tetraazol-1-yl)benzyl]-L-prolinamide (Example 26, Step B, 70 mg, 0.23 mmol, 1.0 equiv), EDC (66 mg, 0.34 mmol, 1.5 equiv) and HOAt (16 mg, 0.11 mmol, 0.5 equiv) in DMF (500 μl) essentially according to the procedure described in Example 26, Step C. Reverse phase HPLC [95:5 water (+0.1% TFA)/CH3CN (+0.1% TFA) to 5:95 water (+0.1% TFA)/CH3CN (+0.1% TFA)] afforded the title compound as a clear oil. 1H NMR (400 MHz, CDCl3): δ 9.16 (s, 1 H), 7.90 (br s, 1 H), 7.59 (s, 1 H), 7.41 (d, J=8.4 Hz, 1 H), 7.24 (d, J =8.4 Hz, 1 H), 4.56 (br s, 1 H), 4.38 (br s, 1 H), 4.18–4.15 (m, 2 H), 3.80 (br s, 1 H), 3.58–3.52 (m, 3 H), 2.15–2.11 (m, 2 H), 2.05–1.98 (m, 2 H), 1.95–1.84 (m, 2 H), 1.70–1.68 (m, 2 H), 1.55 (br s, 2 H), 1.33 (s, 9 H). LCMS (M+H): 518.3.
