실험 절차

To a mixture of (1) (202 mg, 0.99 mmol), 3-(5,7-difluoro-1H-indol-3-yl)propanal ((41), 247 mg, 1.09 mmol) in acetic acid (145 μl, 2.36 mmol) and methanol (10 ml) was added NaBH3CN (126 mg, 2.00 mmol) in portions. Resulting mixture was stirred for 2.0 hr. The solvent was removed in vacuo and the residue was dissolved in CH2Cl2 and washed with 1 N NaOH and saturated NaCl. The organic solution was dried over Na2SO4 and concentrated in vacuo. The compound was purified on silica gel eluting with 70% EtOAc/Hexane to give (18), which was treated with 1 equivalent of etherate HCl to form HCl salt. MS (ES) m/z 412.2.
