Procedure

A mixture comprising 3-amino-6-bromo-5-trifluoromethyl-pyrazine-2-carboxylic acid (Intermediate 2) (0.320 g, 1.118 mmol), 3-aminopyrazolo[3,4-b]pyridine (0.150 g, 1.118 mmol) and HATU (0.425 g, 1.118 mmol) in DMF (5 ml) was treated with N-methylmorpholine (0.111 ml, 1.118 mmol) and stirred at 80° C. overnight. After cooling to RT, the mixture was diluted with water (25 ml) and the resulting yellow precipitate was filtered under vacuum and washed with water. The crude material was purified by chromatography on silica eluting with iso-hexane:EtOAc (gradient of 0 to 100 EtOAc) to give the title compound as a yellow solid.
