Procedure

A mixture comprising 3-amino-6-bromo-5-trifluoromethyl-pyrazine-2-carboxylic acid (Intermediate 2) (0.179 g, 0.624 mmol), 5-amino-4-(pyridin-2-yl)-1H-pyrazole (0.1 g, 0.624 mmol), HATU (0.237 g, 0.624 mmol) and N-methylmorpholine (0.123 ml, 1.249 mmol) in DMF (5 ml) was stirred at 80° C. for 2.5 hours. After cooling to RT, the mixture was diluted with water (40 ml) and the resulting yellow precipitate was filtered under vacuum and washed with water (20 ml). MeOH (150 ml) was added to the solid and the suspension ultrasonicated to give a fine suspension. The suspension was filtered under vacuum and the solid was rinsed with MeOH (20 ml) and dried under vacuum at 45° C. for 1.5 hours to afford the title compound as a yellow solid.
