Reaction Steps

A solution of 17-[2-(6-isopropyl-2-pyridyl)-7-methoxy-8-methylquinolin-4-yloxy]-13-methyl-2,14-dioxo-3,13-diazatricyclo[13.3.0.04,6]octadec-7-ene-4-carboxylic acid (113, 200 mg, 0.31 mmol), DMAP (76.5 mg, 0.62 mmol), and EDC (151 mg, 0.78 mmol) in DMF (5 mL) was stirred at room temperature overnight (the activation of the acid was monitored by LC-MS). Then, cyclopropylsulfonamide (191 mg, 1.56 mmol) was added, followed by DBU (228 μL, 1.56 mmol). The resulting solution was stirred overnight at room temperature, then neutralized with acetic acid and evaporated. The residue was re-dissolved in MeOH and purified by preparative HPLC to give 90 mg (39%) of the title compound 114: m/z=744 (M+H)+.
