Reaction Steps
1.40 g of allyl 5-(4,6-dimethoxypyrimidin-2-yl)oxy-3-dimethylcarbamoyl-2-methylbenzofuran-4-carboxylate and 0.29 g of formic acid were dissolved in 12 ml of tetrahydrofuran, and 37 mg of tetrakistriphenylphosphine palladium (0) was added thereto under a nitrogen atmosphere. The mixture was heated and stirred at 50° C. for 3 hours. The mixture was returned to room temperature, and then isopropyl ether was added to the reaction solution. Precipitated crystals were collected by filtration to obtain 1.02 g (yield: 80%) of the desired compound.
