Vorschrift

The HCl salt of 3-amino-N-(2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-4-yl)propanamide (0.1 mmol) is taken up in 5 mL of DMF along with (4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenoic acid (DHA, 0.1 mmol), HATU (0.11 mmol) and DIEA (0.3 mmol). The resulting reaction mixture is stirred at room temperature for 4 h and then diluted with EtOAc (20 mL). The organic layer is washed with water (3×5 mL), brine (20 mL), dried (Na2SO4) and concentrated under reduced pressure. Purification by silica gel chromatography (95% CH2Cl2, 5% MeOH) affords (4Z,7Z,10Z,13Z,16Z,19Z)-N-(3-((2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-4-yl)amino)-3-oxopropyl)docosa-4,7,10,13,16,19-hexaenamide.
