4-Methylmorpholine → HCID 178458414, compound

Participants

Reaction Steps

To a solution of 5-({[(Z)-(6-bromo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)-2-propoxybenzoic acid (30 mg, 65 μmol) in N,N-dimethylformamide (1 mL) is added 1-hydroxybenzotriazole hydrate (22 mg, 0.16 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (31 mg, 0.16 mmol), and 1-methylmorpholine (25 μL, 0.23 mmol). After shaking at room temperature for 1 hour, to the reaction mixture is added 30% aqueous ammonium hydroxide (5 drops). After 10 minutes of agitation, water is added to the mixture, precipitating a solid, which is collected by filtration, washed with water and methanol, and then dried under house vacuum to give 5-({[(Z)-(6-bromo-1,3-dioxo-2,3-dihydroisoquinolin-4(1H)-ylidene)methyl]amino}methyl)-2-propoxybenzamide (17 mg, 57%).
