Procedure
To a solution of (3-[(5-(4-dimethylamino-phenyl)-furan-2-carbonyl)-amino]-phenyl)-acetic acid ethyl ester (13) (0.33 g) in IMS (80 ml) was added a solution of sodium hydroxide (0.65 g) in water (21 ml). The resulting solution was stirred at room temperature for 1 hour then concentrated in vacuo below 40° C. to circa 15 ml volume. Water (50 ml) then acetic acid (1.5 ml) were added and the resulting precipitate filtered, washed with water and triturated with dichloromethane/pentane to yield the title compound (0.26 g; m.p. 187-190° C.).
