Participants

Reaction Steps

A mixture of 2-(5-methyl-1H-1,2,4-triazol-3-yl)-5-(4-(trifluoromethoxy)phenyl)oxazole (260 mg, 0.83 mmol), 2-chloro-4-(chloromethyl)pyridine (270 mg, 1.66 mmol) and Cs2CO3 (820 mg, 2.5 mmol) in dry DMF (5 mL) was stirred at RT for 72 h. The mixture was then diluted with H2O (50 mL) and extracted with DCM/MeOH (20/1 v/v, 4×50 mL). The combined organic layers were washed with H2O (3×40 mL), brine (50 mL), dried over Na2SO4, filtered and concentrated under reduced pressure to give the crude product, which was purified by silica gel chromatography (DCM:MeOH=20:1 to 15:1) to afford the title compound as a white solid (100 mg, 27%). MS (ES+) C19H13ClF3N5O2 requires: 435. found: 436 [M+H]+.
