Reaction Steps

(S)-5-[3-(9-Methylthio-6-oxo-2,3,3a,4-tetrahydro-1H,6H-5,8,10,10b-tetraazabenzo[e]azulen-5-yl)phenyl]-1,3,4-oxadiazol-2(3H)-one (140 mg, 0.34 mmol) obtained in Step 1 of Example 89 was dissolved in DMF (3.0 mL), and the mixture was stirred at room temperature for 1 hour after adding potassium carbonate (94 mg, 0.68 mmol) and chloroacetone (0.030 mL, 0.38 mmol). Thereafter, water was added to the mixture, and the precipitated pale yellow solid was filtered off to obtain (S)-5-[3-(9-methylthio-6-oxo-2,3,3a,4-tetrahydro-1H,6H-5,8,10,10b-tetraazabenzo[e]azulen-5-yl)phenyl]-3-(2-oxopropyl)-1,3,4-oxadiazol-2(3H)-one (144 mg, 91%).
