الإجراء التجريبي

To a solution of 2-(2,4-bis-benzyloxy-5-isopropyl-benzoyl)-2,3-dihydro-1H-isoindole-5-carbaldehyde (0.316 g, 0.63 mmol) and n-methyl piperazine (63 mg, 0.63 mmol) in CH2Cl2 (10 ml) was added AcOH (38 mgs 0.63 mmol) and NaBH(OAc)3 (0.28 g, 1.33 mmol), then stirred at ambient for 5 hours. The reaction was quenched with water, layers separated and aqueous washed CH2Cl2. The organics were combined, washed with brine, dried (MgSO4), filtered and evaporated to give 0.32 g of (2,4-bis-benzyloxy-5-isopropyl-phenyl)-[5-(4-methyl-piperazin-1-ylmethyl)-1,3-dihydro-isoindol-2-yl]-methanone. MS: [M+H]+ 588.
