Reaction Steps
Analogously to Example 21, 1.00 mmol of 3-amino-4-(3-chloro-phenylamino)-1H-pyrazolo[3,4-d]pyrimidine in 26 ml of methanol, 13 ml of DMEU and 3.0 mmol of acetic acid are first reacted with 2,3-methylenedioxy-benzaldehyde and then reduced with 7.00 mmol of NaCNBH3 (5-7 days). 4-(3-Chloro-phenylamino)-3-(2,3-methylenedioxybenzylamino)-1H-pyrazolo[3,4-d]pyrimidine is obtained; m.p. 214-215° C.; HPLC: TRet (Grad5-40)=24.1.
