A suspension of 4-(4-amino-3-iodo-1H-pyrazolo[3,4-d]pyrimidin-1-yl)-1-pyridiniumolate (0.500 g, 0.0014 mol) in dimethoxyethane (15 mL) and water (30 mL) was reacted with N2-[2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1-methyl-1H-2-indolecarboxamide (0.631 g, 0.00155 mol), sodium carbonate (0.374 g, 0.0035 mol) and tetrakis(triphenylphosphine) palladium (0) (0.163 g, 0.00014 mol) at 80° C. for 18 hours. The solid was filtered and washed with water. The solid was slurried in ethyl acetate for 18 hours and filtered, washing with ethyl acetate. The solid was dried in vacuo to give crude 4-[4-amino-3-(3-methoxy-4-[(1-methyl-1H-2-indolyl)-carbonyl]aminophenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-pyridiniumolate (0.523 g, 0.0010 mol) as a brown solid:
