Triethylamine → HCID 67041495, compound

Participants

Reaction Steps

1-Hexyne (5.16 g, 62.9 mmol) and triethylamine (6.36 g, 62.9 mmol) were sequentially added to a suspension of 2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N-hydroxyethanimidoyl chloride (5.0 g, 21 mmol) in chloroform (80 mL). The solution was stirred overnight at room temperature, washed sequentially with 0.5 M hydrochloric acid and brine, dried over magnesium sulfate, filtered, and concentrated under reduced pressure. The crude product was purified by flash column chromatography on silica gel (eluting with 3:1 to 1:1 hexane:ethyl acetate) to provide 2.14 g of 2-[(5-butylisoxazol-3-yl)methyl]-1H-isoindole-1,3(2H)-dione as a white, crystalline solid.
