| Hazard Information | Back Directory | [Synthesis]
5-Methylpyrazine-2-carboxylic acid (13.81 g, 0.1 mol), tert-butanol (95 mL, 1 mol), triethylamine (27.9 mL, 0.2 mol) and diphenylphosphoryl azide (30.27 g, 0.11 mol) were dissolved in 300 mL of toluene. The reaction mixture was heated to reflux temperature for 8 hours. Upon completion of the reaction, the product was purified by silica gel column chromatography with petroleum ether-ethyl acetate (20:1, v/v) as eluent to afford 15.2 g of N-Boc-2-amino-5-methylpyrazine as a pale yellow solid in 72.7% yield. | [References]
