Procedure

A suspension of 4-[4-amino-3-(3-methoxy-4-{[(1-methyl-1H-2-indolyl)carbonyl]amino}phenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]-1-pyridiniumolate (0.200 g, 0.00039 mol) and 10% palladium on carbon (0.042 g, 0.00004 mol) in acetic acid (3 mL) was reacted with sodium hypophosphite monohydrate (0.063 g, 0.00059 mol) at 60° C. for 2 hours. Additional 10% palladium on carbon (0.042 g, 0.00004 mol) and sodium hypophosphite (0.045 g, 0.00042 mol ) was added and the mixture was stirred for 24 hours. The solvent was removed in vacuo and the residue was slurried in methanol for 4 hours. The mixture was filtered through Celite® 521, washing with methanol. The solvent was removed in vacuo and the residue was purified by preparative RP-HPLC (Rainin C18, 8 mm, 300 A, 25 cm; 50% isocratic for five minutes, then 50%-100% acetonitrile-0.1M ammonium acetate over 25 min, 21 ml/min). The acetonitrile was removed in vacuo and the aqueous mixture was lyopholyzed to give N2-{4-[4-amino-1-(4-pyridyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-1-methyl-1H-2-indolecarboxamide (0.020 g, 0.00004 mol) as a white solid:
