Reaction Steps

2-[3,5-Diallyloxy-2-ethyl-6-(4-methoxybenzoyl)-phenyl]-N-(2-hydroxyethyl)-N-(2-morpholinoethyl)acetamide (0.31 g, 0.55 mmol) obtained in Example 110, Step 2 was dissolved in 1,4-dioxane (1.5 mL), and ammonium formate (0.14 g, 2.2 mmol) and bis(triphenylphosphine)palladium (II) dichloride (0.012 g, 0.017 mmol) were added thereto, followed by stirring at 100° C. for 1.5 hours in an atmosphere of argon. The reaction mixture was cooled to room temperature and then concentrated under reduced pressure. The resulting residue was purified by C18 silica gel column chromatography (water-water/acetonitrile=1/1) to obtain Compound III (0.14 g, 51%).
