Reaction Steps

To a stirred mixture of 2-(5-methyl-1H-1,2,4-triazol-3-yl)-4-(4-(trifluoromethoxy)phenyl)thiazole (3 g, 9.2 mmol) and Cs2CO3 (4.8 g, 13 mmol) in DMF (20 mL) was added 2-chloro-4-(chloromethyl)pyridine (2.1 g, 13 mmol). The mixture was stirred at RT for 16 h, then diluted with H2O (20 mL) and extracted with EtOAc (3×30 mL). The combined organic layers were washed with H2O (20 mL), concentrated under reduced pressure and the residue was purified by silica gel column chromatography (Petroleum ether:EtOAc=4:1) to afford the title compound as an oil (2.1 g, 50.6%).
