実験手順: 2.5 g of 12,12-difluorododec-11-enoic acid methyl ester are added at room temperature to 1.53 g of 4-trimethylsilylaniline in 25 ml of toluene. The mixture is stirred for 2 hours at 80° and then concentrated by evaporation in vacuo. The residue is taken up in toluene, the toluene phase is washed with water, dried over sodium sulfate and concentrated to dryness by evaporation. The residue is taken up in hexane:ethyl acetate (9:1) and filtered over silica gel. Evaporation of the filtrate yields the title compound (nD24 =1.5038; compound no. 1-2). concentrated by evaporation in vacuo the toluene phase is washed with water dried over sodium sulfate concentrated to dryness by evaporation filtered over silica gel Evaporation of the filtrate

実験手順: With cooling at 10°, 1.0 g of 6,6-difluorohex-5-enoic acid chloride is added to 1.0 g of 4-trimethylsilylaniline, 0.73 g of trithylamine and 10 mg of 4-N-pyrrolidinopyridine in 25 ml of tetrahydrofuran. The mixture is stirred for 2 hours at room temperature and then concentrated by evaporation in vacuo. The residue is taken up in toluene, the toluene phase is washed with water, dried over sodium sulfate and concentrated to dryness by evaporation. The residue is taken up in hexane:ethyl acetate (9:1) and filtered over silica gel. Evaporation of the filtrate yields the title compound having a melting point of 50°-51° (compound no. 1-1). With cooling at 10° concentrated by evaporation in vacuo the toluene phase is washed with water dried over sodium sulfate concentrated to dryness by evaporation filtered over silica gel Evaporation of the filtrate
