Reaction Steps

A mixture of N-cyclopropyl-3-fluoro-4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (520 mg, 1.63 mmol), 5-bromo-1-(2,6-difluorophenyl)-7-methyl-1H-pyrazolo[4,3-b]pyrazin-6(7H)-one (505 mg, 1.48 mmol) in 3.5 mL of dioxane and 1.5 mL of 2 N Na2CO3 was heated in a microwave at 125° C. for 25 min. It was diluted with EtOAc and washed with 1 N NaOH. The EtOAc layer was separated, dried and concentrated. Purification of the crude material on an ISCO 40 g column (with 30-75% EtOAc in Hexanes) provided N-cyclopropyl-3-(1-(2,6-difluorophenyl)-7-methyl-6-oxo-6,7-dihydro-1H-pyrazolo[4,3-b]pyrazin-5-yl)-5-fluoro-4-methylb enzamide as an off white amorphous solid. MS (ES+): 454.1 (M+H)+.
