실험 절차

To a solution of triphenyl-(3,3,3-trifluoro-propyl)-phosphonium iodide (146 mg, 0.30 mmol) in anhydrous dioxane (10 mL) at 0 C under nitrogen was added potassium tert-butoxide (34 mg, 0.3 mmol) portion-wise. The suspension was stirred for 10 min at 0 C and then added drop-wise to a solution of 1-{3-[4-amino-6-(methyl-phenyl-amino)-[1,3,5]triazin-2-yl]-[1,2,4]oxadiazol-5-yl}-piperidin-4-one (Intermediate 131, 55 mg, 0.150 mmol) in anhydrous dioxane (10 mL). The resulting reaction mixture was stirred at room temperature for 16 h and evaporated to dryness. The solid obtained was dissolved in DCM (25 mL) and washed with water (25 mL), a saturated ammonium chloride aq. solution (25 mL) and brine (25 mL). The organic phase was dried over magnesium sulfate, evaporated to dryness and purified by preparative HPLC-MS (Method B) to afford the title compound as an off-white solid (8 mg, 12%).
