To a mixture of 2-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-5-{5-fluoro-2-(methyloxy)-3-[(E)-2-(methyloxy)ethenyl]phenyl}-1,3-thiazole (D79) (100 mg) in tetrahydrofuran (THF) (20 mL) under nitrogen was added HCl (0.5 mL). The reaction was heated to 70° C. for 2 h. The mixture was filtered and the filtrate was concentrated to give the crude product [3-(2-{3-chloro-4-[(1-methylethyl)oxy]phenyl}-1,3-thiazol-5-yl)-5-fluoro-2-(methyloxy)phenyl]acetaldehyde (D80) (90 mg) as a brown oil. MS (ES): C21H19ClFNO3S requires 419. found 420.1 (M+H+).
