実験手順
(S)-Azetidine-1,2-dicarboxylic acid 1-benzyl ester (45.7 mg, 0.19 mmol) was dissolved in DMF (1.5 mL). Triethylamine (53 μL, 0.38 mmol) and pentafluorophenyl trifluoroacetate (33 μL, 0.19 mmol) were added, and the reaction was stirred at ambient temperature for 30 minutes. Then 4-(2-Amino-thiazol-4-yl)-N-cyclopropyl-benzamide trifluoroacetic acid salt (62.9 mg, 0. 17 mmol) was added. The reaction was stirred at ambient temperature overnight and then heated to 70° C. for 4 hours. The reaction was cooled, filtered, and purified by reverse phase HPLC to give the desired product. Yield 7.2 mg. MS: 477.1 (M+H+); H1 NMR (DMSO-d6): δ(ppm) 0.50-0.85 (m, 4H), 2.10-2.30 (m, 1H), 2.48-2.62 (m, 1H), 2.78-2.90 (m, 1H), 3.80-4.07 (m, 2H), 4.80-5.13 (m, 3H), 7.07-7.42 (m, 4H), 7.78-7.99 (m, 5H), 8.40-8.47 (m, 1H), 12.40-12.58 (m, 1H).
