Abstract:
The present invention relates to processes for preparing methyl {4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]pyrimidin-5-yl}carbamate, i.e. the compound of the formula (I) and to a process for purifying the crude product of the formula (I) for use as pharmaceutically active compound, where, for purification, methyl {4,6-diamino-2-[1-(2-fluorobenzyl)-1H-pyrazolo[3,4-b]pyridin-3-yl]pyrimidin-5-yl}carbamate sulphinyldimethane (1:2) of the formula (II) is isolated as intermediate or is generated as intermediate in this purification process, if appropriate present in a mixture.
