Procedure

N-bromosuccinimide (44 mg, 0.249 mmol) was added into a solution of methyl 5-(7-amino-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)piperidine-2-carboxylate (100 mg, 0.249 mmol) in acetonitrile (1.5 mL) and methanol (0.5 ml). The resulting solution is stirred at room temperature for 1 hour. The reaction was concentrated in vacuo and purified by prep-LC to afford the title compound (22.32 mg): LC/MS RT=2.56 min. Mass calculated for, M+H 481.09, observed 481.09.
