As an example, N-(3-(6-((3-fluoro-4-morpholinophenyl)amino)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)phenyl)acrylamide can be prepared according to Route II. Beginning with 4,6-dichloro-1H-pyrazolo[3,4-d]pyrimidine, protection can be accomplished by reaction with 3,4-dihydro-2H-pyran. The resulting 4,6-dichloro-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-d]pyrimidine can then be coupled with (3-acrylamidophenyl)boronic acid under palladium catalyzed conditions to provide N-(3-(6-chloro-1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)phenyl)acrylamide.
