7-bromo-2,3-dihydroinden-1-one

Conditions: temp:90.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred solution of 10.4 g (112 mmol) of aniline in 60 ml of toluene 5.31 g (28.0 mmol) of TiCl4 was added for 30 min at room temperature in argon atmosphere. The resulting mixture was stirred at 90° C. for 30 min followed by an addition of 6.00 g (28.0 mmol) of 7-bromoindan-1-one. The resulting mixture was stirred for 10 min at 90° C., poured into 500 ml of water, and crude product was extracted with 3×100 ml of ethyl acetate. The organic layer was separated, dried over Na2SO4, and then evaporated to dryness. The residue was crystallized from 10 ml of ethyl acetate at −30° C. The resulting solid was separated and dried in vacuum. After that it was dissolved in 100 ml of methanol, 2.70 g (42.9 mmol) of NaBH3CN and 0.5 ml of glacial acetic acid was added. The resulting mixture was refluxed for 3 h in argon atmosphere. The resulting mixture was cooled to room temperature and then evaporated to dryness. The residue was diluted with 200 ml of water, and crude product was extracted with 3×50 ml of ethyl acetate. The combined organic extract was dried over Na2SO4 and evaporated to dryness. The residue was purified by flash chromatography on silica gel 60 (40-63 um, eluent: hexane-ethyl acetate-triethylamine=100:10:1, vol.). Yield 5.50 g (68%) of a yellow oil.
