실험 절차

Sodium azide (1.80 g; 27.65 mmol) was added to a solution of 4-(triethylsilyl)but-3-ynyl 4-methylbenzenesulfonate (3.12 g; 9.22 mmol) in DMF (15 mL) and stirred at 60° C. for 3 hours. After cooling, the volatiles were removed under reduced pressure and the residue was partitioned between saturated ammonium chloride and ethyl acetate. The organic layer was dried and concentrated under reduced pressure to afford 2.0 g (quantitative yield) of (4-azidobut-1-ynyl)triethylsilane as a colorless oil.
