실험 절차
Compound B (1.20 g, 3.02 mmol) was dissolved in 20 ml of dimethylformamide. To the solution were added 1.04 g (7.55 mmol) of potassium carbonate and subsequently 0.38 ml (6.04 mmol) of methyl iodide, and the resultant mixture was stirred at 50° C. for 30 minutes. After cooling, insoluble matters were filtered off, and 400 ml of water was added to the flit rate. The mixture was extracted three times with 100 ml of chloroform. The extract was washed twice with water and once with a saturated aqueous solution of sodium chloride, and dried over anhydrous sodium sulfate, followed by evaporation under reduced pressure. The residue was purified by silica gel column chromatography (eluent: 1% methanol/chloroform), followed by recrystallization from propanol/water to give 1.22 g (yield 98%) of Compound 1 as white needles.
