Versuchsvorschrift

Using the procedure of Step F of Example 9, (1R,cis) 2,2-dimethyl-3-[(Z) 3-oxo-3-(2-fluoroethoxy)-1-propenyl]-cyclopropane-carboxylic acid prepared as in Example 21 except 2-fluoroethanol was used and (3-propargyl-2,5-dioxo-imidazolidinyl)-methanol were reacted to obtain (3-propargyl-2,5-dioxo-1-imidazolidinyl)-methyl (1R,cis) 2,2-dimethyl-3-[(Z) 3-oxo-3-(2-fluoroethoxy)-1-propenyl]-cyclopropane-carboxylate with a specific rotation of [α]D20 =+18°±2° (c=1% in CHCl3)
