Reaction Steps

To a suspension of 6-iodo-3-(3-(trifluoromethyl)phenyl)-[1,2,4]triazolo[4,3-a]pyridine (0.101 g, 0.26 mmol) and tetrahydro-2H-pyran-4-amine (0.131 g, 1.30 mmol) in toluene (1 mL) was added rac-Binap (0.049 g, 0.078 mmol), Pd(OAc)2 (0.012 g, 0.052 mmol) and Cs2CO3 (0.169 g, 0.52 mmol). It was flushed with argon then heated at 110° C. overnight. It was absorbed on SiO2 and purified on column chromatography on SiO2 with 60% 15% MeOH/EA in hexane. This product was further purified on C18 column chromatography using 20-40% ACN in water.
