実験手順

At room temperature, a solution of 1.5 g (0.01 mol) of 2-methyl-4,5-dihydrofuran-3-carbonyl chloride in 10 ml of toluene is added dropwise with stirring to a mixture of 2.2 g (0.01 mol) of 4-fluoro-2-cyclooctylaniline, 1.0 g of triethylamine and 40 ml of toluene. After the addition has ended, the reaction mixture is stirred at room temperature for another 2 hours. The reaction mixture is subsequently admixed with water. The organic phase is separated off, dried over sodium sulphate and then concentrated under reduced pressure. The residue that remains is stirred with hexane. The resulting crystalline product is filtered off with suction and dried at 50° C. under reduced pressure. In this manner, 2.2 g (66.7% of theory) of N-(4-fluoro-2-cyclooctyl)-2-methyl-4,5-dihydrofuran-3-carboxanilide are obtained in the form of a solid substance of melting point 91° C.
