Reaction Steps

1-(4-Fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid (2-bromo-thiazol-5-ylmethyl)-amide (50 mg, 0.10 mmol) was treated with a 2 M solution of methylamine in THF (2.0 mL, 4.0 mmol) in a microwave tube. To this solution was added solid K2CO3 (19 mg, 0.14 mmol), and the microwave tube was sealed and heated at 100° C. for 1 hour in a microwave. The mixture was then heated at 160° C. in a microwave for 4 hours, and the mixture was diluted with saturated aqueous ammonium chloride (40 mL) and EtOAc (20 mL). The layers were separated and the organics layer was washed with brine (50 mL), dried over sodium sulfate, filtered and concentrated. The crude material was purified by silica gel chromatography eluting with a gradient of 0-10% methanol in dichloromethane to afford the title compound.
