6-Bromo-1-methylene-indan 38c (4.91 g, 23.5 mmol) was dissolve in ethyl acetate followed by addition of palladium on carbon (0.98 g). The reaction mixture was reacted at room temperature for 4 hours under hydrogen atmosphere. The reaction was monitored by TLC until the disappearance of the starting materials. The mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound 6-bromo-1-methyl-indan 38d (3.11 g, yield 62.7%) as a colourless oil.
