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-methylsulfonylpiperazine (0.214 g, 1.303 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 2 hr and was concentrated under reduced pressure. Water was added to the residue. The mixture was filtered to produce a crude yellowish-green solid, which was washed with methanol to produce a purified product (0.325 g) in 57.3% yield.
