Procedure: The title compound was prepared from 4-bromo-3-fluorophenol and 2,2,3,3,3,-pentafluoropropyl triflate with potassium carbonate in acetone at ambient temperature for 18 hours. Kugelrohr distillation provided a colorless oil, b.p. 105-110° C./12 mbar. Kugelrohr distillation provided a colorless oil, b.p. 105-110° C./12 mbar

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

Procedure: Using 0.50 g of (4-(trifluoromethyl)benzyl)malononitrile, 5 ml of N,N-dimethylformamide, 363 mg of cesium carbonate, and 0.63 g of 2,2,3,3,3-pentafluoropropyl trifluoromethanesulfonate, and according to the process described in the Production Example 1, there was obtained 0.20 g of 2-(2,2,3,3,3-pentafluoropropyl)-2-(4-(trifluoromethyl)benzyl)malononitrile (the present compound (76)).

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

Procedure: Using 0.3 g of (4-(trifluoromethoxy)benzyl)malononitrile, 5 ml of N,N-dimethylformamide, 0.073 g of cesium carbonate, and 0.35 g of 2,2,3,3,3-pentafluoropropyl trifluoromethanesulfonate, and according to the process described in the Production Example 1, there was obtained 0.12 g of 2-(2,2,3,3,3-pentafluoropropyl)-2-(4-(trifluoromethoxy)benzyl)malononitrile (the present compound (5)).

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

Procedure: A mixture of trifluoromethanesulfonic anhydride (40 mL, 0.24 mol) and 2,2,3,3,3-pentafluoropropanol (25 mL, 0.24 mol) was heated under argon at 90° C. overnight. Then, the crude mixture was distilled at atmospheric pressure to give the desired product as a colourless oil (97% yield). Then, the crude mixture was distilled at atmospheric pressure

Procedure: In a manner analogous to that described in example 24 a), the alkylation of the 5-hydroxy-pyridine-2-carboxylic acid methyl ester with potassium carbonate and trifluoro-methanesulphonic acid 2,2,3,3,3-pentafluoropropyl ester yielded the 5-(2,2,3,3,3-pentafluoro-propoxy)-pyridine-2-carboxylic acid methyl ester as a light yellow oil. MS (ISP): m/z=285 [M]+.
