Reaction Steps

Sodium thiomethoxide (0.3 g, 3.79 mmol) was added to a solution of 1-(4-chlorobutyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-amine (1.0 g, 3.16 mmol) in 15 mL of DMF and heated for 3 hours at 80° C. The reaction mixture was allowed to cool to ambient temperature, diluted with dichloromethane, and washed with water. The aqueous layer was extracted with several additional portions of dichloromethane and the combined organic layers were washed with water, washed with brine, dried over magnesium sulfate, and concentrated to afford 1.04 g of 1-(4-methylthiobutyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-amine as a yellow solid.
