실험 절차

To a solution of 1-{[(5S,7S)-7-methyl-2-oxo-1-oxa-3-azaspiro[4.5]dec-7-yl]methyl}-1H-benzimidazole-6-carbonitrile (1.0 g, 3.08 mmol) in N,N-Dimethylformamide (DMF) (7 mL) was added 60% sodium hydride in mineral oil (0.160 g, 4.01 mmol) and stirred for 30 minutes. To the mixture was added 4-bromo-2-(bromomethyl)pyridine (0.928 g, 3.70 mmol) and stirred overnight. The reaction was diluted with saturated NH4Cl and extracted with ethyl acetate (3×). The combined organic extracts were washed with saturated NaCl (2×), dried over Na2SO4, filtered, and concentrated. The residue was purified via silica gel chromatography (ISCO, 120 g silica, 60 mL/min, 0-10% MeOH/CH2Cl2 over 45 min) to afford 1-(((5S,7S)-3-((4-bromopyridin-2-yl)methyl)-7-methyl-2-oxo-1-oxa-3-azaspiro[4.5]decan-7-yl)methyl)-1H-benzo[d]imidazole-6-carbonitrile (1.41 g, 93%). MS (m/z) 494.1 (M+).
