[0419] ##STR00040##
[0420] n-Butyl lithium (2.5 M in hexanes, 100 mL, 248.9 mmol) was added slowly to a solution of diisopropyl amine (35.2 mL, 248.9 mmol) in tetrahydrofuran (400 mL) at −70° C. The resulting solution was aged for 30 min at −70° C. and then ethyl 4,4,4-trifluorobutyrate (36 g, 207.4 mmol) was added drop wise. The reaction was stirred for 2 h at −70° C., benzyl bromide (43.2 g, 248.9 mmol) was added and the reaction mixture was gradually warmed to room temperature over ca. 2 h. Saturated NH.sub.4Cl solution was added and the mixture was extracted with methyl tertbutyl ether.

Example B5: Fusarium culmorum (Root Rot)
[0559] Conidia of the fungus from cryogenic storage were directly mixed into nutrient broth (PDB potato dextrose broth). A DMSO solution of the test compounds was placed into a microtiter plate (96-well format) and the nutrient broth containing the fungal spores was added to it. The test plates were incubated at 24 C and the inhibition of growth was determined photometrically after 48 hrs.

A DMSO solution of the test compounds was placed into a microtiter plate (96-well format) and the nutrient broth containing the fungal spores was added to it. The test plates were incubated at 24 C and the inhibition of growth was determined photometrically after 7 days at 620 nm.
