実験手順
2-Bromo-5,6-dimethyl-8-propyl-3-thia-1,4,7,8a-tetraaza-as-indacene was dissolved in 5 mL of methanol and sodium methoxide (4.98 mg, 0.092 mmol) was added. The resulting mixture was stirred at 60° C. for 1 h. LC-MS showed complete consumption of 2-bromo-5,6-dimethyl-8-propyl-3-thia-1,4,7,8a-tetraaza-as-indacene. After removal of the solvent under reduced pressure, 5 mL of water and 10 mL of EA were added. The organic layer was concentrated, crude product was purified by prep-HPLC to give 4 mg of the title compound.
