Procedure

6-Bromo-3-(quinolin-3-yl)-5-(1,2,3,6-tetrahydropyridin-4-yl)pyrazolo[1,5-a]pyrimidin-7-amine (0.035 mmol) was charged to a 20 mL scintillation vial. Then DMF (1 ml), N,N-diisopropylethylamine (0.14 mmol, 25 μL), thiophene-2-carboxylic acid (0.039 mmol, 5 mg), and EDC (0.039 mmol, 7.4 mg) were added, respectively. The resulting reaction mixture was stirred at room temperature for 18 hours. Upon completion, the reaction mixture was concentrated in vacuo and purified via reverse-phase preparatory HPLC to yield (4-(7-amino-6-bromo-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-5,6-dihydropyridin-1(2H)-yl)(thiophen-2-yl)methanone (m+H=531.06, retention time=3.74 min). Also recovered was the dehalogenated product, (4-(7-amino-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-5,6-dihydropyridin-1(2H)-yl)(thiophen-2-yl)methanone (m+H=453.24, retention time=3.51 min).
