실험 절차

To a round bottom flask containing methanol (16 mL) was added 1,3,5-tribenzoylbenzene (0.250 g, 0.640 mmol). This was stirred under nitrogen and heated to reflux. Thiosemicarbazide (0.05536 g, 0.608 mmol) was then added to the flask, followed by p-toluenesulfonic acid (0.00122 g, 0.0064 mmol). The reaction mixture was stirred at reflux for 14 h. The crude mixture was purified using column chromatography, eluting with 35% ethyl acetate in hexanes, however the product still contained impurities and was submitted for testing without further purification. HRMS (ESI) calculated for C28H21O2N3SH+ (M+H)+ 464.14272, found 464.14267. Compound 25 was estimated to be approximately 80% pure by NMR, and was submitted for biological testing without further purification.
