Procedure
The reaction was also carried out using 0.14 g (0.59 mmol) of the commercially available 1-butyl-3-methyl-imidazolium acetate with 0.11 g (0.29 mmol) of 2-(2-pentanoyloxy-5-nitrophenyl)-1-(4-methoxyphenyl)-ethanone (example 2) under the same reaction conditions as described in example 18. By comparing the LC-MS chromatogram of the crude reaction mixture with the chromatogram obtained from the reaction with 1-butyl-3-methyl-imidazolium valerate it was concluded that both methods delivered the targed compound in similar yield.
