Reaction Steps

Pyridine (198 mg; 2.5 mmol; 5.0 eq.) was added to a solution of N5-cyclohexyl[1,2,4]triazolo[1,5-a]pyridine-2,5-diamine ((A9), 116 mg; 0.50 mmol; 1.0 eq.) in DCM (2.0 mL). 6-(chloromethyl)pyridine-3-carbonyl chloride hydrochloride (190 mg; 1.0 mmol; 2.0 eq.) was added and the resulting black solution was stirred under reflux for 14 h. The solvents were evaporated to yield a black oil. Morpholine (218 mg; 2.5 mmol; 5.0 eq.) and THF (0.5 mL) were added to this residue, and the mixture was then stirred and heated at 60° C. for 12 h. Purification by RP-HPLC (Waters Sunfire™ Prep C18 OBD™ 5 μM, 100×49 mm) following a gradient starting with 20/80 (0.1% formic acid in CH3CN/0.1% formic acid in H2O) up to 95/5 in 12 min. The fractions were collected and lyophilized to give the title compound as a white powder (20 mg, 9%). HPLC, Rt: 2.11 min. (purity 100%). LC/MS, M+(ESI): 436.3.
