Reaction Steps

To a solution of 4-(2,4-Dimethyl-5,6,7,8-tetrahydronaphthalen-1-yl)-5-(trifluoromethyl)-4H-1,2,4-triazole-3-thiol (0.2 g, 0.611 mmol) in THF (2.44 mL) was added ethyl 2-bromoacetate (68 μL, 0.611 mmol) and potassium carbonate (0.17 g, 1.22 mmol), and the mixture heated at 60° C. for 18 hours. The mixture was concentrated, ethyl 2-bromoacetate (68 μL, 0.611 mmol) and DMF (1.2 mL) added, and the mixture heated at 60° C. for 24 hours. Water (40 mL) was added and the mixture extracted with ethyl acetate (2×40 mL). The combined organic extracts were washed with brine, dried over sodium sulfate, filtered, concentrated and purified by SGC (0-50% ethyl acetate/Hexanes) to afford ethyl 2-(4-(2,4-dimethyl-5,6,7,8-tetrahydronaphthalen-1-yl)-5-(trifluoromethyl)-4H-1,2,4-triazol-3-ylthio)acetate as a clear oil (0.137 g, 54%).
