Reaction Steps
Compound 54 (390 mg, 1.01 mmol) obtained in Reference Example 51 was dissolved in 10 ml of dimethylformamide. To the solution were added 0.20 ml (2.50 mmol) of ethyl iodide and 420 mg (3.04 mmol) of potassium carbonate, and the mixture was stirred overnight at room temperature. Water was added thereto to dissolve potassium carbonate and deposited crystals were collected by filtration. The collected-crude crystals were recrystallized from hexane/ethyl acetate to give 237 mg (yield 53%) of Compound 55 as pale yellow needles.
