Versuchsvorschrift

(2S,3S)-3-Hydroxy-pyrrolidine-1,2-dicarboxylic acid 1-benzyl ester (41.9 mg, 1.6 mmol) and HATU (66.3 mg, 1.7 mmol) were dissolved in DMF (2 mL). DIEA (55 μL, 0.32 mmol) was then added, and the reaction was stirred at ambient temperature for 15 minutes. Then 4-(2-Amino-thiazol-4-yl)-N-cyclopropyl-benzamide trifluoroacetic acid salt (62.9 mg, 0.17 mmol) was added, and the reaction was stirred at ambient temperature overnight. The reaction was filtered and purified by reverse phase HPLC to give the desired product. Yield 11.8 mg. MS: 507.2 (M+H+); H1 NMR (DMSO-d6): δ(ppm) 0.50-77 (m, 4H), 1.70-2.10 (m, 2H), 4.20-4.40 (m, 1H), 4.86-5.17 (m, 2H), 7.00-7.42 (m, 4H), 7.74-8.01 (m, 5H), 8.40-8.48 (m, 1H), 12.58-12.67 (m, 1H).
