24%; 53% With thionyl chloride; for 5h;Heating / reflux; REFERENCE EXAMPLE 1; Preparation of alpha,alpha,alpha-trifluoromethacrylic acid benzyl esterInto a 500 ml two-necked round-bottomed flask equipped with a condenser and a stirrer, alpha,alpha,alpha-trifluoromethacrylic acid (154.0 g, 1.10 mol) and thionyl chloride (170.1 g, 1.43 mol) were charged and refluxed for 5 hours. By distillation, alpha,alpha,alpha-trifluoromethacrylic acid chloride (92.6 g) having a boiling point of from 88 to 92C, was obtained (yield: 53%). Further, as a byproduct, alpha,alpha,alpha-trifluoromethacrylic acid anhydride (34.0 g) having a boiling point of 106C/31 mmHg was obtained (yield: 24%).

The reaction mixture was stirred for 2 h, diluted by DCM, washed with water and brine, dried over NA2SO4, filtered and concentrated. The residue was purified by flash column chromatography (silica gel, 5 % EtOAc/hexane) to yield the product (13.7 g, 42 %) as a viscous oil. 1H-NMR (400MHz, CDCl3) 8 7.36-7. 43 (m, 5H), 6.78 (d, 1H), 6.48 (d, 1H), 5.32 (s, 2H).

With sulfuric acid; at 80℃; for 2h; [SYNTHESIS EXAMPLE 3]; Synthesis of 2-trifluoromethylacrylate represented by the following formula (9); Concentrated sulfuric acid (0.50g, 5.10mmol) was added dropwise at room temperature to a mixture of the crude product (1.00g, 2.55mmol) of the formula (7) and 2-trifluoromethylacrylic acid (0.71g, 5.10mmol), followed by stirring at 80C for 2hr. By an analysis of the reaction liquid by gas chromatography, conversion to the formula (9) was 82.0%, and the raw material alcohol (7) was in 13.1%. The reaction liquid was poured into iced water, followed by extraction of the organic matter with diethyl ether. Then, the organic layer was washed with saturated sodium hydrogencarbonate aqueous solution, pure water and saturated brine, followed by drying with magnesium sulfate anhydride. Then, the solvent was removed by evaporator, followed by a separation purification by silica gel column chromatography to obtain the formula (9) (0.82g, 1.59mmol, purity: 92.3GC%) as a colorless, transparent liquid.

93.0% With sodium hydroxide; sulfuric acid; In toluene; EXAMPLE 1 Synthesis of 2-methyl-2-adamantyl alpha-trifluoromethylacrylate [MAFAC] A 500 ml flask was flushed with nitrogen to displace the air with nitrogen, and was charged with 70.0 g (0.50 mol) of alpha-trifluoromethylacrylic acid (supplied from Tosoh F-tech Inc.), 1.0 g (10 mmol) of sulfuric acid and 100 g of toluene. Separately 88.8 g (0.60 mol) of 2-methyleneadamantane, prepared by the same procedures as described in Reference Example 1, was dissolved in 100 g of toluene. The obtained solution of 2-methyleneadamantane in toluene was dropwise added to the content in the flask over a period of about 3 hours, while the content was maintained at a reaction temperature of about 5 C. Then the content was stirred for 15 hours at the same temperature. After completion of the reaction, the residual catalyst was neutralized by adding 40.0 g (50 mmol) of a 5% aqueous sodium hydroxide solution, and the neutralized liquid was washed with an aqueous saturated sodium chloride solution. The thus-obtained organic phase was subjected to column chromatography, and further, analyzed by NMR and mass spectrometry. Thus, 133.9 g (yield: 93.0%) of the object 2-methyl-2-adamantyl alpha-trifluoromethylacrylate was obtained.

With hydrogenchloride; sodium nitrite;copper(I) chloride; In acetone; Step A Synthesis of 2-chloro-2-trifluoromethyl-3-[3-fluoro-4-(1-methyl-6-trifluoromethyl-2,4(1H,3H)-pyrimidinedion-3-yl)phenyl]propanoic acid as an intermediate This compound was prepared in a manner analogous to that of Step E of Example 1, using 6.0 grams (0.020 mole) of 3-(4-amino-2-fluorophenyl)-1-methyl-6-trifluoromethyluracil (prepared as in Step D of Example 1), 28.0 grams (0.200 mole) of 2-trifluoromethylpropenoic acid, 1.4 grams (0.020 mole) of sodium nitrite, 0.5 gram (0.005 mole) of copper(I) chloride, and 30 mL of concentrated hydrochloric acid in 150 mL of acetone, yielding 5.8 grams of 2-chloro-2-trifluoromethyl-3-[3-fluoro-4-(1-methyl-6-trifluoromethyl-2,4(1H,3H)-pyrimidinedion-3-yl)phenyl]propanoic acid. The NMR spectrum was consistent with the proposed structure. This reaction differed from Step E of Example 1 in that the intermediate propene used here was the acid, rather than the methyl ester, as was used in Step E of Example 1.
YieldReaction ConditionsOperation in experiment
80% EXAMPLE 25 To a mixed solution of 50 ml of DMF and 10 ml of acetic acid, was added 0.6 g of copper acetate and the mixture was heated at 40-50 C. Then 19.6 g (or 0.3 gram atom) of commercial zinc powder was added to the mixture and agitated for 30 min. After cooled, the mixture was washed 4 times with 25 ml of DMF to obtain zinc-copper couple. The same procedure was followed as in Example 16, except that the zinc-copper couple was used. As a result, alpha-trifluoromethylacrylic acid was obtained with a yield of 80%.
