実験手順
A solution of 3-[4-(5-tert-butyl-2-methyl-phenylethynyl)-phenyl]-acrylic acid ethyl ester (Intermediate 111, 0.09 g, 0.26 mmol) in ethanol (3 mL) and tetrahydrofuran (3 mL) was treated with 3M potassium hydroxide solution (1 mL, 3 mmol) and the resulting reaction mixture was stirred overnight at ambient temperature. The reaction mixture was concentrated in vacuo slightly, the residue was neutralized with dilute hydrochloric acid, and the solid that was formed was filtered and washed with water and acetonitrile and dried to afford title product (0.064 g, 77%).
