실험 절차
A mixture of 3-bromo-6-cyano-pyridine (2 g, 10.9 mmol), sodium azide (0.85 g, 13 mmol), and ammonium chloride (0.59 g, 11 mmol) in N,N-dimethylformamide (20 mL) was heated for 1 h at 120° C. The reaction mixture was diluted with ethyl acetate (˜100 mL) and the product was isolated by filtration and then washed with ethyl acetate to give the title compound, an off-white amorphous solid which was used in the next step without further purification.
