Triethylamine → HCID 178448496, compound

Participants

Reaction Steps

A mixture of (4E)-6-iodo-4-(methoxymethylene)isoquinoline-1,3(2H,4H)-dione (170 mg, 0.51 mmol) and 4-aminomethyl-1-butyl-1H-pyridin-2-one trifluoroacetate (150 mg, 0.51 mol) is stirred in dimethylformamide (2.7 mL) at room temperature in the presence of triethylamine (0.33 mL) for 18 hours. The reaction mixture is concentrated under reduced pressure. The residue is purified via semi-preparative HPLC (Prodigy ODS3 column, 5% acetonitrile/95% water/0.01% trifluoroacetic acid to 100% acetonitrile at 10 mL/min) to give (4Z)-6-iodo-4-({[(1-butyl-2-oxo-1,2-dihydropyridin-4-yl)methyl]amino}methylene)isoquinoline-1,3(2H,4H)-dione as an peach colored solid (25 mg, 10% due to substantial loss of material during HPLC malfunction).
