실험 절차

A mixture of (2,4-bis-benzyloxy-5-isopropenyl-phenyl)-(4-hydroxy-1,3-dihydro-isoindol-2-yl)-methanone (2 g; 4.07 mmol), 4-(3-chloropropyl)morpholine (1.66 g; 2.5 equiv.) and caesium carbonate (8.3 g; 6.25 equiv) in DMF was heated at 90° C. overnight then evaporated. The residue was dissolved in EtOAc, washed with brine, dried (MgSO4) and evaporated. Purification of the crude material using a Biotage SP4 (40S, 40 ml/min), using gradient elution form 0% to 10% MeOH/EtOAc gave 1.8 g of (2,4-bis-benzyloxy-5-isopropenyl-phenyl)-[4-(3-morpholin-4-yl-propoxy)-1,3-dihydro-isoindol-2-yl]-methanone as a pale yellow gum. MS: [M+H]+ 619.
