Reaction Steps

In a dried reaction flask, 2-(3-chloro-4-cyanophenyl)-3-cyclopentyl-3,3a,4,5-tetrahydro-2H-pyrazolo[3,4-f]quinoline-7-carboxylic acid (0.421 g, 1.0 mmol), 1-methylpiperazine (144 mg, 1.437 mmol), DIEA (0.2 mL, 1.15 mmol), and HATU (0.418 g, 1.1 mmol) were added to a mixed solvent of DMF (4 mL) and dichloromethane (8 mL). The mixture was stirred at room temperature for 1.5 hr and was concentrated under reduced pressure. Water was added to the residue. The mixture was filtered to produce a crude yellow solid, which was washed with methanol to obtain a purified product (0.253 g) in 50.3% yield.
