Phenethylamine → HCID 23587943, compound

Participants

Reaction Steps

To a solution of 4-oxo-6,7-dihydropyrido[2,1;a]isoquinoline-3-carboxylic acid (3-101-03) (76 mg) in DMF (2.0 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloric acid salt (EDC, 83 mg), 1-hydroxybenzotriazole (HOBt, 58 mg), and phenethylamine (80 mg) at room temperature. After the reaction mixture was stirred for 18 h, the reaction was quenched with 0.5 mol/L hydrochloric acid. To the reaction mixture was added ethyl acetate and the organic layer was separated. The aqueous layer was extracted three times with ethyl acetate, and the combined organic layers were washed with water and brine, dried over anhydrous magnesium sulfate, and evaporated under reduced pressure. The obtained crude crystal was recrystallized to give 4-oxo-6,7-dihydropyrido[2,1,a]isoquinoline-3-carboxylic acid phenethylamide (3-101) (84 mg, 74%) as an yellow crystal.
