실험 절차

To a stirred solution of 1-methyl-5-((3-((S)-phenyl((((R)-quinuclidin-3-yloxy)carbonyl)amino)methyl)phenoxy)methyl)-1H-pyrazole-3-carboxylic acid (0.30 g, 0.61 mmol) in DMF (6 mL) was added triethylamine (0.2 mL, 1.53 mmol), 4-aminobutyraldehyde diethyl acetal (0.20 mL, 1.22 mmol), EDCI (0.18 g, 0.91 mmol) and 2-hydroxypyridine-N-oxide (0.09 g, 0.91 mmol). The reaction mixture stirred at RT for 90 h. The reaction mixture was diluted with ethyl acetate and washed with saturated sodium hydrogen carbonate, brine, dried (magnesium sulfate), filtered and the solvent evaporated at reduced pressure to afford the crude target material (0.22 g, 57%) which was used directly without further purification.
