Participants

Reaction Steps

Triethylamine (184 μL, 1.32 mmol), HOBt (89 mg, 0.66 mmol), 3-amino-6-fluoro-3,4-dihydro-2(1H)-quinolinone monohydrochloride (CAS Reg. No: 82420-54-0) (143 mg, 0.66 mmol), and EDAC (127 mg, 0.66 mmol) were added to a solution of 5-chloroindole-2-carboxylic acid (129 mg, 0.66 mmol) in anhydrous DMF (3.5 mL). The reaction was stirred at ambient temperature for approximately 16 h, and then poured into water (50 mL). This was stirred vigorously for about 10 mins. and filtered. The collected precipitate was washed with water and dried in vacuum at 40° C., to give the title compound (200 mg, 85%) as an amorphous solid.
