실험 절차

The suspension of 5-oxo-5,6,7,8-tetrahydronaphthalen-2-yl trifluoromethanesulfonate (1.8 g, 6.1 mmol), 3-methylbenzene-1-thiol (0.76 g, 6.1 mmol), Pd2(dba)3 (142 mg, 0.153 mmol), Xantphos (177 mg, 0.306 mmol) and DIEA (1.58 g, 12.2 mmol) in 1,4-dioxane (60 mL) was stirred at reflux overnight under N2. The reaction was filtered and concentrated. Purification by silica gel chromatography (PE:EtOAc=5:1) gave 1.8 g (100%) of the title compound as an orange oil. [M+H] Calc'd for C17H16OS, 269. Found, 269.
