Reaction Steps

(S)-5-[3-(5-Mercapto-1,3,4-oxadiazol-2-yl)phenyl]-9-methylthio-1,2,3,3a,4,5-hexahydro-5,8,10,10b-tetraazabenzo[e]azulen-6-one (37 mg, 0.09 mmol) obtained in Step 1 was dissolved in DMF (1.0 mL), and the mixture was stirred at room temperature for 1 hour after adding potassium carbonate (36 mg, 0.26 mmol) and methyl iodide (0.012 mL, 0.19 mmol). Thereafter, water was added to the mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The resulting residue was then purified by silica gel column chromatography to give (S)-9-methylthio-5-[3-(5-methylthio-1,3,4-oxadiazol-2-yl)phenyl]-1,2,3,3a,4,5-hexahydro-5,8,10,10b-tetraazabenzo[e]azulen-6-one (23 mg, 59%).
