실험 절차

To a solution of the above (R)-1-(6-bromo-pyridin-3-yl)-ethylamine HCl salt (500 mg, 1.82 mmol) in DMF (10 mL) was added 1-{[(R)-5-(4-Cyano-benzyl)-7-(3,5-dichloro-4-fluoro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-α]imidazole-3-carbonyl]-amino}-cyclopropanecarboxylic acid (900 mg, 1.66 mmol) and diisopropylethylamine (1.45 mL, 8.30 mmol). The mixture was stirred at room temperature for 5 min. HATU (694 mg, 1.83 mmol) was added to the mixture and the clear yellow mixture was stirred for 17 h. The mixture was diluted with ethyl acetate (35 mL) and washed with water (8 mL). The organic phase was washed with 5% aqueous NaCl solution (2×10 mL) and brine (20 mL), dried over Na2SO4, filtered, and concentrated to pale yellow oil. The crude oil was purified via flash chromatography on silica gel, eluting with 1-6% MeOH/CH2Cl2, to afford 1.3 g of the title compound as a yellow foam.
