Reaction Steps

To a stirred solution of methyl 2-bromo-7-(2,4-dichlorophenyl)-5-methyl-[1,2,4]-triazolo[1,5-a]pyrimidine-6-carboxylate (30 mg, 0.07 mmol) in dioxane (2 mL) was added thiomorpholine (15 μL, 0.14 mmol). After heating to 75° C. for 16 h, the reaction was concentrated under reduced pressure and diluted with EtOAc. The organic layer was washed with satd aq NH4Cl and brine prior to drying over anhydrous MgSO4. Filtration, concentration under reduced pressure and purification by silica gel chromatography afforded methyl 7-(2,4-dichlorophenyl)-5-methyl-2-thiomorpholino-[1,2,4]-triazolo[1,5-a]pyrimidine-6-carboxylate (28 mg, 90%) as a yellow solid.
