2,4-dimethyl-2,3-dihydroinden-1-one

Conditions: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 36 g (270 mmol) of AlCl3 were added to 17.7 g (90 mmol) of acid chloride f4 in 50 ml of toluene in the course of 20 minutes, and the mixture was stirred at 80° C. for 4 hours. It was poured onto ice/HCl, extracted with toluene, washed with H2O, NaHCO3 solution and NaCl solution, dried and distilled (109° C./1 mmHg) or chromatographed (n-hexane/ethyl acetate 6:1, rF =0.44). It was poured onto ice/HCl extracted with toluene washed with H2O, NaHCO3 solution and NaCl solution dried distilled (109° C./1 mmHg) chromatographed (n-hexane/ethyl acetate 6:1, rF =0.44)
