Reaction Steps

3-(5-Chloro-2-methoxy-phenyl)-1-methyl-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidin-6-ylamine trifluoroacetate is dissolved in 48% HBr in water (10 ml) and heated using microwave radiation at 120° C. for 2 hours. Purification of the reaction mixture by preparative HPLC (water/acetonitrile, 0.1% TFA) affords the title compound as the minor product of the reaction as the trifluoroacetate salt.
