Reaction Steps

A 2M LDA solution in THF (4.16 ml, 8.32 mmol) was added to a solution of indanone (1.00 g, 7.57 mmol) in THF (10 ml) at −60° C. The solution was slowly warmed to 0° C. during a period of 15 min. and was agitated for 15 more min. The reaction was then cooled to −78° C. and a solution of methyl-4-bromobenzoate (1.73 g, 7.57 mmol) was slowly added. The solution was slowly warmed to −20° C. and stirred during 4 hours. The reaction mixture was quenched with HCL 1M and the solvent was evaporated. The residue was diluted in ethyl acetate, washed with brine, dried over anhydrous MgSO4, filtered and concentrated. The crude residue was then purified by flash chromatography on silica gel (5-20% AcOEt/HEx) to afford the title compound 271(245 mg, 17%) as a white solid. LRMS: 280.1 (Calc.). 281.1 (found).
