6-Aminohexanoic Acid → 1,3-Dihydro-1,3-dioxo-2H-isoindole-2-hexanoic acid

참여 물질

반응 단계

Combine 6-aminohexanoic acid (6-aminocaproic acid) (8.0 g, 60 mmol) and water (100 mL). Add sodium carbonate (6.84 g, 64 mmol) and N-carbethoxyphthalimide (14.0 g, 64 mmol). After 1.5 hours, extract the reaction mixture with ethyl acetate (100 mL). Cool the aqueous layer in an ice bath and acidify using concentrated hydrochloric acid to give a solid. Collect the solid by filtration, rinse with water, and dry to give 6-phthalimidohexanoic acid (12.7 g, 80% yield).
