Versuchsvorschrift

4-(tert-Butoxycarbonylamino)tetrahydro-2H-pyran-4-carboxylic acid (374 mg), (S)-2-amino-3-(4′-cyanobiphenyl-4-yl)propanamide (Example 3, step (iii), 405 mg) and N-ethyl-N-isopropylpropan-2-amine (0.664 mL) were dissolved in DMF (10 mL) and to the solution was added TBTU (734 mg). The reaction mixture was stirred at room temperature for 2 days. The reaction mixture was evaporated to dryness, dissolved in dichloromethane (20 mL) and was absorbed onto silica. The product was purified by chromatography on silica eluting with 20% ethyl acetate in isohexane, then 50% ethyl acetate in isohexane and then 100% ethyl acetate to afford after evaporation of the relevant fractions the sub-titled compound (700 mg).
