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 (7 mL) was added potassium carbonate (111 mg, 0.80 mmol) and 1-(bromomethyl)-4-(methylsulfonyl)benzene (100 mg, 0.402 mmol) and the resultant reaction mixture was heated to 80° C. for 16 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, 0-30% ethyl acetate in pet ether) afforded title compound as a solid (30 mg, 24%).
