実験手順
To a stirring solution of 1-((2,3-dimethoxy-6-(1-oxo-2,3-dihydro-1H-inden-4-yl)phenoxy)methyl)cyclopropyl methanesulfonate (3 g, 6.72 mmol) in dimethylformamide (20 mL), was added sodium azide (2.18 g, 33.63 mmol) and the resultant reaction mixture was stirred at RT for 16 h. The reaction mixture was quenched with ice water and extracted with ethyl acetate (3×). The combined ethyl acetate layer was washed with brine, dried over anhydrous sodium sulphate and concentrated under reduced pressure. Purification by column chromatography (silica gel, 0-5% ethyl acetate in pet ether) to afforded 4-(2-((1-(azidomethyl)cyclopropyl)methoxy)-3,4-dimethoxyphenyl)-2,3-dihydro-1H-inden-1-one as a liquid.
