실험 절차

A solution of 2,4-bis-benzyloxy-5-isopropenyl-benzoic acid (210 mg, 0.56 mmol) and diisopropylethylamine (0.25 mL, 1.4 mmol) in DCM (5 mL) was treated with bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (PyBrOP) (287 mg, 0.62 mmol). After 1 hour a solution of 4-(3-morpholin-4-yl-propoxy)-2,3-dihydro-1H-isoindole (0.56 mmol, assuming a quantitative yield from the preceding step (C18)) in DCM (5 mL) was added. After 4 hours the mixture was diluted with ethyl acetate and washed with water, 1N sodium hydroxide solution and brine. The organic phase was dried (MgSO4) and concentrated to give a residue which was absorbed onto an SCX column. This was washed with 10% methanol/DCM then the product was eluted with 25% 2M methanolic ammonia/DCM) to afford an impure sample of the intermediate (2,4-bis-benzyloxy-5-isopropenyl-phenyl)-[4-(3-morpholin-4-yl-propoxy)-1,3-dihydro-isoindol-2-yl]-methanone.
