Reaction Steps

A poly(tetrafluoroethylene)-lined steel pressure vessel containing a solution of 2-benzyl-1-methyl-2H-pyrazolo[3,4-c]quinolin-4-amine (prepared as described in Example 36, 0.8821 g, 3.06 mmol) in anhydrous hydrogen bromide in acetic acid (10 mL) was heated in a 140° C. oven for 17 hours. The vessel was allowed to cool to room temperature. A solid formed that was isolated by filtration and washed with water to yield 1-methyl-2H-pyrazolo[3,4-c]quinolin-4-amine that was used in the next step.
