Participants

Reaction Steps

To a stirred solution of 2-{1-[(1-{[(R)-5-(4-cyano-benzyl)-7-(3,5-dichloro-phenyl)-5-methyl-6-oxo-6,7-dihydro-5H-imidazo[1,2-a]imidazole-3-carbonyl]-amino}-cyclopropanecarbonyl)-amino]-cyclopropyl}-isonicotinic acid (30 mg, 0.044 mmol), in 3 mL DMF was added HATU (25 mg, 0.66 mmol) diisopropylethylamine (0.3 mL) and 2-amino-2-methyl-propan-1-ol (5.8 mg, 0.66 mmol). The solution was allowed to stir at room temperature overnight (18 h). The reaction was diluted with water (5 mL), then extracted with a 5% methanol/dichloromethane solution (3×10 mL). The organic layers were combined, dried (MgSO4) and concentrated. The resulting oil was purified by reversed phase HPLC to afford 28 mg of the title compound, m/z 755.7.
