Procedure
A mixture of 7-benzyloxy-4-chloro-2-ethyl-2H-pyrazolo[3,4-c]quinoline (1.20 g, 3.55 mmol) and 7 N ammonia in methanol (25 mL) was heated in a pressure vessel at 150° C. for 24 hours. The reaction mixture was concentrated under reduced pressure, purified via column chromatography on silica gel (eluting with 0-35% CMA/chloroform), concentrated under reduced pressure, and crystallized from acetonitrile to yield 0.93 g of 7-(benzyloxy)-2-ethyl-2H-pyrazolo[3,4-c]quinolin-4-amine as a tan solid, mp 229-230° C.
