Procedure

(R)-5-(4-(Piperidin-4-yl)phenylamino)-3-(3-(piperidine-1-carboxamido)piperidin-1-yl)-1,2,4-triazine-6-carboxamide hydrochloride (494) (70 mg, 0.13 mmol) was dissolved in 4 mL DMF. To it were added DIEA (230 μL, 1.30 mmol) and then propionyl chloride (36 μL, 0.39 mmol). The mixture was stirred at RT for 1 hour, quenched with 0.3 mL TFA, and directly subjected to reverse phase prep HPLC to isolate the title compound, (R)-3-(3-(piperidine-1-carboxamido)piperidin-1-yl)-5-(4-(1-propionylpiperidin-4-yl)phenylamino)-1,2,4-triazine-6-carboxamide (498), as HCl salt (45 mg). LC-MS (ESI): m/z (M+1) 564.3. UV: λ=263, 329, 338 nm.
