Reaction Steps

A mixture of 3-amino-2-(2-chloro-5-hydroxyphenyl)-2,5-dihydro-4H-pyrazolo[4,3-c]quinolin-4-one (65 mg), triethylamine (31 μl), acetyl chloride (15 μl) and dichloromethane (1.7 ml) was stirred at room temperature for 12 hours. The reaction mixture was poured into water and extracted with ethyl acetate. The extract was washed with brine and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and chloroform-hexane was added to the residue. The precipitated solid was collected by filtration to obtain the target compound (52 mg).
