Here is a downstream synthesis route of the compound, Product Details of 709652-82-4, blongs to pyridine-derivatives compound. Product Details of 709652-82-4

Imidodicarbonic acid, 2-[5-bromo-3-(cyano)-2-pyridinyl]-,1,3-bis(1,1-dimethylethyl)ester To 2-amino-5-bromonicotinonitrile (0.785 g, 3.96 mmol), triethylamine (0.553 mL, 3.96 mmol) and 4-dimethylaminoyridine (20 mg, 0.164 mmol) in CH2Cl2 (25 mL) was added di-tert-butyl-dicarbonate (2.16 g, 9.91 mmol) and the resulting mixture stirred at room temperature for 18 h. Evaporated to dryness in vacuo and triturated in heptane (25 mL) for 72 h. The resulting precipitate was filtered and washed with heptane (10 mL) to give imidodicarbonic acid, 2-[5-bromo-3-(cyano)-2-pyridinyl]-,1,3-bis(1,1-dimethylethyl)ester as a beige solid (1.1 g, 70% yield). 1H NMR (400 Mhz, CDCl3, 298K) 1.51 (s, 18H) 8.16 (d, 1H) 8.77 (d, 1H). LCMS: [M+H]+=398/400.1, Rt(4)=1.43 min.
