Procedure

A solution of 6-ethenyl-1-[3-fluoro-4-(methyloxy)phenyl]-4-(methyloxy)-1H-indole (D9) (200 mg, 0.67 mmol) in ethanol (7 mL) and ethyl acetate (7 mL) was hydrogenated in an H-cube over a 10% palladium on charcoal catalyst. The resulting solution was concentrated and the product purified by silica gel chromatography eluting with 5-70% dichloromethane in hexane to yield the title compound (D10), (180 mg).
