N-bromobutanimide → HCID 66738157, compound

Participants

Reaction Steps

N-bromosuccinimide (148 mg, 0.832 mmol) was added to a solution of 4-{7-[bis-(2-trimethylsilanyl-ethoxymethyl)-amino]-3-quinolin-3-yl-pyrazolo[1,5-a]pyrimidin-5-yl}-cyclohexanecarboxylic acid methyl ester (500 mg, 0.756 mmol) in acetonitrile (10 mL). The reaction mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated in vacuo and the resulting oil is then purified via silica gel chromatography (0% to 30% ethyl acetate in hexanes gradient) to yield the title compound (530 mg, 95% yield) as yellow oil. LC-MS: 740 [M+H].
