The synthetic route is as follows., category: Pyrazines
(iv) 3-Amino-6-bromopyrazine-2-carboxylic acid: To a solution of the product of step (iii) (200 g, 0.86 mol) in MeOH (500 mL) was added 5 N-NaOH (500 mL) slowly. The resulting mixture was stirred at 50 C for 3 hours. MeOH was removed under a reduced pressure and water (300 mL) added to the reaction mixture. The solution was acidified to pH 3 with 6N-HC1. The solution was extracted with EtOAc and washed with water. The combined organic extract was dried over Na2S04, filtered and evaporated to dryness to afford the subtitle compound (iv) as a brown yellow solid (180 g). 1H-NMR (400 MHz, CDC13) delta 8.30 (s, 1H);HPLC Retention Time = 0.850min.
