反応手順

Lenalidomide (200 mg, 0.771 mmol) was taken up in 5 mL of CH3CN and 2 mL of DMF along with (4Z,7Z,10Z,13Z,16Z,19Z)-docosa-4,7,10,13,16,19-hexaenoic acid (DHA, 253 mg, 0.771 mmol), HATU (322 mg, 0.848 mmol) and DIEA (200 μL, 2.3 mmol). The resulting reaction mixture was stirred at room temperature for 3 h and diluted with EtOAc (20 mL). The organic layer was washed with water (3×5 mL), brine, dried (Na2SO4) and concentrated under reduced pressure. Purification by silica gel chromatography (95% CH2Cl2, 5% MeOH) afforded 280 mg of (4Z,7Z,10Z,13Z,16Z,19Z)-N-(2-(2,6-dioxopiperidin-3-yl)-1-oxoisoindolin-4-yl)docosa-4,7,10,13,16,19-hexaenamide (63%). MS (EI) calculated for C35H43N3O4: 569.33; found: [M+H]+ 570.
