Reaction Conditions

Reaction Steps

CDI (13.50 mg, 0.083 mmol) was added to a stirred, room temperature mixture of (R)-5-(2-(4-fluorophenyl)-6-((1-(4-fluorophenyl)ethyl)carbamoyl)-1-oxo-1,2-dihydroisoquinolin-3-yl)pentanoic acid (28 mg, 0.055 mmol) in tetrahydrofuran (2 mL) and the mixture was stirred at 70° C. for 2 h. DBU (0.017 mL, 0.111 mmol) and cyclopropylsulfonamide (10.09 mg, 0.083 mmol) were added, the resultant mixture was kept stirring at room temperature overnight. The mixture was concentrated, and the residue was purified via PTLC (Emerck 1 mm), eluted with CH2Cl2/MeOH=10:1 to give (R)-3-(5-(cyclopropanesulfonamido)-5-oxopentyl)-2-(4-fluorophenyl)-N-(1-(4-fluorophenyl)ethyl)-1-oxo-1,2-dihydroisoquinoline-6-carboxamide (16 mg) as a white solid.
