反応手順

To a reaction vessel containing N5-cyclopropyl-7-(trifluoromethyl)[1,2,4]triazolo[1,5-a]pyridine-2,5-diamine ((A18), 77 mg, 0.3 mmol, 1 eq.) and pyridine (0.063 mL, 1.2 mmol, 4 eq.) in dichloromethane (1 mL) was added 4-dimethylaminomethyl-benzoyl chloride (118 mg, 0.6 mmol, 2 eq.) as a solution in dichloromethane (2 mL), dropwise. The vessel was capped and heated to reflux for approximately 16 hours. The reaction mixture was cooled and the solvent removed in vacuo. The residue dissolved in DMSO (1.5 mL) and purified by reverse phase preparatory HPLC to give the title compound as a white solid (65.1 mg, 52%). HPLC, Rt: 2.59 min (purity: 100%). LC/MS M+(ESI): 419.2, M−(ESI) 417.2.
