Versuchsvorschrift

Diisopropylethylamine (7.00 g, 64.2 mmol) was added to a solution of 3-(thiophene-2-carbonyl)amino-L-alanine, methyl ester hydrochloride (Example 301; 7.00 g, 26.4 mmol), 2-chloro-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]benzoic acid (Example 26; 7.00 g, 22.9 mmol), and HBTU (13.00 g, 34.3 mmol) in DMF (75 mL). The solution was allowed to stir at room temperature for 4 days, and it was then concentrated to remove most of the DMF. Ethyl acetate (200 mL) was added, followed by water (200 mL) and 1 M HCl (100 mL). The layers were separated; the ethyl acetate layer was evaporated, and the residue was chromatographed (50-100% ethyl acetate/hexanes) to give N-[2-chloro-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine, methyl ester (8.30 g, 70%) as a white solid.
