実験手順

With cooling with ice, 2.6 g of sodium azide was added to a concentrated hydrochloric acid (60 mL) solution of 5 mL of alpha-tetralone, and stirred at room temperature for 15 hours. The reaction liquid was poured into ice water, and neutralized with potassium carbonate. This was extracted with chloroform, and the organic layer was washed with saturated saline water and dried with anhydrous magnesium sulfate. The solvent was evaporated away under reduced pressure, and the crude product was purified through silica gel column chromatography (chloroform/methanol) to obtain 2.3 g of the entitled compound as a yellow solid.
