Citric Acid → HCID 21921391, compound

Participants

Reaction Steps

To a solution of 4-biphenylacetic acid (1.0 g, 4.7 mmol) in 10 ml of anhydrous DMF was added HBTU (2.1 g, 5.7 mmol) and 1.0 ml of DIEA. The mixture was stirred at room temperature for 10 min, and then 1-bromo-3-isoquinolinamine (0.68 g, 4.7 mmol) was added. After stirring over night, the mixture was poured into water, acidified with 10% citric acid, and extracted with ethyl acetate. The organic extracts were washed with water and brine, dried over Na2SO4. After the condensation of the solvent, the residue was purified by flash column chromatography (SiO2, 1:1 hexane:ethyl aceate) to provide the title compound (1.7 g, 86%) as a light yellow solid.
