Reaction Conditions

Reaction Steps

A mixture of 1-ethyl-4-chloro-6-acetamido-1H-pyrazolo[3,4-b]quinoline (0.2 g, 0.7 mmol), cyclohexanemethylamine (0.5 ml, 3.5 mmol) and DMSO (3 ml) was heated at 110° C. for 6 hours. The reaction mixture was poured into water (50 ml), extracted with CH2Cl2 (4×25 ml) and the organic layers were combined and evaporated. The residue was slurried in ether and a yellow solid was collected by filtration and recrystallized from ethanol/ethyl acetate to afford 200 mg of 1-ethyl-6-acetamido-N-(cyclohexylmethyl)-1H-pyrazolo[3,4-b]quinolin-4-amine, m.p. 277°-278° C.
