실험 절차
The tert-butyl 3-{3-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-6-cyano-2-methoxy-5-methylphenyl}azetidine-1-carboxylate (0.35 g, 0.73 mmol) (Step 7, peak 1) was dissolved in methylene chloride (3.0 mL) and trifluoroacetic acid (1.0 mL) at room temperature. After stirring for 1 h the reaction was complete by LC/MS. The reaction was concentrated in vacuo to give 4-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-2-azetidin-3-yl-3-methoxy-6-methylbenzonitrile (bis(trifluoroacetate) as a viscous amber oil (0.50 g, 100%). LCMS calculated for C20H24N7O (M+H)+: m/z=378.2; found: 378.2.
