Yield	Reaction Conditions	Operation in experiment
	With potassium dihydrogenphosphate In 1,4-dioxane; water at 60℃; for 9h;	4 0.547 g of 2,6-dibromo-4-tert-butylanisole (synthesized by the method described in Tetrahedron.Lett,1999,36,919), 0.844 g of 1-N-Boc-pyrrole-2-boronic acid (manufactured by Frontier Scientific), 0.138 g of tris(benzylideneacetone)dipalladium, 0.247 g of 2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl, and 5.527 g of potassium phosphate were dissolved in mixed solvent of 200 mL of dioxane and 20 mL of water, and the solution was stirred at 60°C for 9 hours. After the completion of the reaction, the solution was left standing to cool, distilled water and chloroform were added to the solution, and an organic layer was extracted. The resultant organic layer was concentrated, whereby a black residue was obtained. The residue was purified with a silica gel column, whereby Compound (D) was obtained. 1H-NMR(300MHz,CDCl3)δ1.30(s,18H), 1.31(s,9H), 3.19(s,3H), 6.19(m,2H), 6.25(m,2H), 7.22(s,2H), 7.38(m,2H)
