Reaction Steps

5-Chloro-3-(morpholin-4-ylmethyl)-N-pyrimidin-4-yl-1-[2-(2,2,2-trifluoroethoxy)ethyl]-1H-pyrazolo[4,3-d]pyrimidin-7-amine trifluoroacetate (150 mg, 0.2 mmol), (R)(−)-2-methylpiperazine (86 mg, 0.85 mmol) and N,N-diisopropylethylamine (140 mg, 1.0 mmol) were mixed in methyl sulfoxide (1.0 ml) in a reaction vial. The reaction mixture was heated at 110° C. for 18 hours. The reaction was cooled to room temperature and brought to acidic condition by adding trifluoroacetic acid. The crude reaction mixture was purified on reverse phase HPLC (5-95% acetonitrile in water with 0.05% trifluoroacetic acid) and lyophilized to give 5-[(3R)-3-methylpiperazin-1-yl]-3-(morpholin-4-ylmethyl)-N-pyrimidin-4-yl-1-[2-(2,2,2-trifluoroethoxy)ethyl]-1H-pyrazolo[4,3-d]pyrimidin-7-amine trifluoroacetate (143 mg).
