2-AZIDOTOLUENE SOLUTION

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of sodium hydride (60% in oil, 280 mg) in DMF (10 ml) was cooled to 0° C.-5° C., methyl 7-methoxy-3-oxoheptanoate (1.32 g) was added, and the mixture was stirred at 0° C.-5° C. for 30 min. Then, 1-azido-2-methylbenzene (932 mg) was added, and the mixture was stirred at room temperature for 15 hr. The solvent was concentrated under reduced pressure, methanol (10 ml) was added to the residue, and 4N aqueous sodium hydroxide solution (5 ml) was added and the mixture was stirred at 60° C. for 1 hr. The solvent was evaporated under reduced pressure and water (20 ml) was added to the residue. 6N Hydrochloric acid was added for neutralization and the mixture was extracted with ethyl acetate (20 ml×2). The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate was concentrated under reduced pressure to give the object product (930 mg) as an oil. the mixture was stirred at room temperature for 15 hr The solvent was concentrated under reduced pressure, methanol (10 ml) was added to the residue, and 4N aqueous sodium hydroxide solution (5 ml) was added the mixture was stirred at 60° C. for 1 hr The solvent was evaporated under reduced pressure and water (20 ml) was added to the residue 6N Hydrochloric acid was added for neutralization the mixture was extracted with ethyl acetate (20 ml×2) The extract was dried over anhydrous sodium sulfate the solvent was evaporated under reduced pressure a fraction eluted with ethyl acetate was concentrated under reduced pressure
