Reaction Steps

A stream of dry hydrogen chloride was passed through a solution of 1-chloro-N′-[4-cyano-2-(4-methanesulfonyl-phenyl)-2H-pyrazol-3-yl]-N,N-dimethyl-formamidine (0.600 g, 1.70 mmol) in 1,2-dichloroethane (20 mL) for 1 h. The solution was stirred at rt for 3 days. The solvent was removed under reduced pressure and the crude washed several times with dichloromethane. [4-Chloro-1-(4-methanesulfonyl-phenyl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl]-dimethyl-amine recrystalized in dichloromethane and it was retrieved by filtration as an off-white solid (0.4 g, 67%). Exact mass calculated for C14H14ClN5O2S 351.06, found 352.20 (MH+, 100%).
