N-bromobutanimide → HCID 46945342, compound

Participants

Reaction Steps

To crude 5-(morpholinomethyl)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-7-amine (44 mg) in CH3CN (8 mL) was added N-bromosuccinimide (22 mg, 0.12 mmol), followed by additional CH3CN (4 mL). The reaction was then stirred at room temperature for 30 minutes, at which time LC/MS analysis confirmed full conversion of the starting material to the product. The reaction mixture was concentrated in vacuo and purified by preparative HPLC to give 6-bromo-5-(morpholinomethyl)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-7-amine as a yellow solid (8.7 mg, 0.02 mmol, 7% over three steps). LCMS: 0.82 mins, m/z=439.0 and 441.0 (MH+).
