Reaction Steps
A solution of 3-(4-ethoxycarbonylmethyl-3-fluoro-phenylethynyl)-benzoic acid isopropyl ester (Intermediate 138, 0.1 g, 0.27 mmol) in isopropanol (2 mL) and tetrahydrofuran (2 mL) was treated with a 2M solution of lithium hydroxide (1 mL, 2 mmol). After 40 min. at ambient temperature, the reaction mixture was concentrated in vacuo a bit, neutralized with 10% hydrochloric acid and the solid formed was filtered, washed with water and dried to afford the title compound (0.09 g, 97%).
