Reaction Steps

The title compound was made in a similar way as that of example 134, step a, from 3-(1-hydroxyethyl)-4-(4-((4-methylpiperazin-1-yl)methyl)phenyl)-1H-isochromen-1-one (Intermediate B46, 750 mg, 1.982 mmol) and 3-(3-fluoro-5-methoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (Intermediate G1, 565 mg, 2.18 mmol) to give 3-(1-(4-amino-3-(3-fluoro-5-methoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl)-4-(4-((4-methylpiperazin-1-yl)methyl)phenyl)-1H-isochromen-1-one (98 mg, 0.158 mmol, 7.98% yield) as a brown solid.
