実験手順

tert-Butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-5,6-dihydropyridine-1(2H)-carboxylate (0.071 mmol, 50 mg) was charged to a 20 mL scintillation vial containing 1 mL acetonitrile. To this solution was added N-bromosuccinimide (0.078 mmol, 14 mg). The reaction mixture was allowed to stir at room temperature for 1 hour. After 1 hour, the reaction was concentrated in vacuo and the crude intermediate was dissolved in 1 mL TFA. The reaction mixture was stirred for 1 hour at room temperature and concentrated in vacuo to yield 6-bromo-3-(quinolin-3-yl)-5-(1,2,3,6-tetrahydropyridin-4-yl)pyrazolo[1,5-a]pyrimidin-7-amine as yellow solid.
