Procedure

To a stirring solution of 4-(4-ethoxy-2-hydroxy-3-methoxyphenyl)-2,3-dihydro-1H-inden-1-one (80 mg, 0.268 mmol) in acetonitrile was added potassium carbonate (111 mg, 0.805 mmol) and propyl bromide (99 mg, 0.805 mmol) and the resultant reaction mixture was heated to 80° C. for 4 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure. Purification of the residue by flash column chromatography (silica gel, 0-20% ethyl acetate in pet ether) afforded title compound as a solid (7 mg, 7.7%).
