Reaction Steps

To an oven-dry microwave tube was added 2-fluoro-N-(3-oxo-3,4-dihydro-2H-benzo[1,4]thiazin-6-yl)-nicotinamide (150 mg, 0.5 mmol), C-(1H-pyrrolo[2,3-b]pyridin-4-yl)-methylamine hydrochloride salt (220 mg, 1.0 mmol), DIEA (1 mL), and t-BuOH (2 mL). The resulting mixture was sealed off and underwent microwave heating at 170° C. for 20 min. Solvent was removed in vacuo. The crude solid was purified by chromatography on silica gel. Elution with DCM:MeOH mixture (97:3) gave final compound. MS (ES+): 430.6 (M+H). Calc'd. for C22H18N6O2S—430.49.
