실험 절차

To a solution of 8-amino-2,3,8,9-tetrahydropyrano[3,2-e]isoindol-1(7H)-one (1) (200 mg, 0.98 mmol) in anhydrous MeOH (20 ml) was added 3-(5-fluoro-1H-indol-3-yl) propanal (2) (191 mg, 1 mmol), AcOH (0.14 ml), and NaBH3CN (123 mg, 1.96 mmol). Resulting reaction mixture was stirred at room temperature for 2 hr. The solvent was removed in vacuo and the residue was re-dissolved in CH2Cl2 (150 ml). The solution was washed with 1 N NaOH (20 ml) and H2O, Sat. NaCl. The organic solution was separated, dried over Na2SO4, then concentrated in vacuo. The crude compound was purified on silica gel eluting with EtOAc/Hexane (4:1) to yield (3) (304 mg, 82%) as a white solid. MS (APPI) m/z 380.
