실험 절차

To a solution of (R)-5-(4-Cyano-benzyl)-7-(3,5-dichloro-4-fluoro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-carboxylic acid (85 mg, 0.19 mmol) and (S)-2-Amino-N-(1-pyrimidin-2-yl-cyclopropyl)-propionamide (49 mg, 0.18 mmol) in THF (1.0 mL) and DMF (0.7 mL), was added HATU (80 mg, 0.21 mmol) followed by DIPEA (0.15 mL, 0.88 mmol). The reaction was stirred at room temperature for 20 h. The THF was removed under a stream of N2 and the reaction mixture was purified by reverse phase HPLC. The purified material was then passed through a basic amino group functionalized solid phase extraction cartridge to give 80 mg of the title compound as a solid, m/z 647.34 [M+1]+.
