Step 5. Methyl 2-bromo-5H-pyrrolo[2,3-b]pyrazine-7-carboxylate. To a 0 C. suspension of 2-bromo-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (145 g, 602 mmol) in MeOH (1.5 L) was added dropwise SOCl2 (93 g, 781 mmol) over a period of 40 min. after the addition, the resulting mixture was heated to reflux for 4 hours, which time suspended solution became clear and then yellow solid was precipitated. TLC (petroleum ether/EtOAc, 1:1) showed starting material was consumed completely. The reaction mixture was evaporated to dryness, which was triturated with MTBE to give methyl 2-bromo-5H-pyrrolo[2,3-b]pyrazine-7-carboxylate (109 g, 71%) as a yellow solid.
