Participants

Reaction Steps

4-[10-(2,5-Dioxopyrrolidin-1-yloxycarbonyl)decyl]benzoic acid tert-butyl ester (300 mg, 0.65 mmol) was dissolved in DMF (3 ml) and 4-amino butyric acid (67 mg, 0.65 mmol). The mixture was stirred for 16 h under nitrogen. The solvent was removed under vacuum and AcOEt (35 ml) was added. The solution was washed with 0.2 N HCl and water (15 ml each). Sat. NaHCO3 was added (not intended) to the organic phase. DCM (50 ml) was added. Some of the organic phase was removed and DCM (100 ml) was added to the aqueous phase and allowed to stand overnight. The mixture was cooled on ice and the pH was adjusted to 1.9 with 4N HCl. The organic phase was isolated, dried over MgSO4 and concentrated under vacuum to yield on oil (220 mg, 76% yield).
