实验步骤: A 100 ml round bottom flask fitted with a reflux condenser and a magnetic stirrer was charged with 8.8 grams (0.1 mol) of ethylene glycol monovinyl ether, 14.5 grams (0.12 mol) of allyl bromide, 4.8 grams (0-12 mol) of NaOH, 0.9 grams (3 mol %) of (n-Bu)4NBr, and 20 ml of dried toluene. The white suspension was stirred and heated at 65 ° C. for 12 hours. After cooling the reaction mixture, the resulting light yellow solution was separated from the white solids by decantation and washed with four times with 50 ml portions of water in a separatory funnel. Removal of the solvent under reduced pressure followed by vacuum distillation (b.p. 30° C./0.15 mm Hg gave the desired 1-allyloxy-2-vinyloxyethane as a colorless liquid.

实验步骤: To a mixture of hydoxyethyl vinyl ether (500 g) and tetra-n-butyl ammonium hydrogen sulfate (50 g), an aqueous solution of sodium hydroxide (340 g) dissolved in water ax (380 ml) was added over 30 minutes and then further stirred at room temperature for 1 hour. Further, chloromethyloxysilane (78.8 g) was added thereto and stirred at 60° C. for 2 hour. Then, ethyl acetate was added to the reaction mixture, followed by washing with water. The organic layer was extracted and dried with magnesium sulfate, and condensed at reduced pressure to distill off the solvents. The resulting liquid was purified by vacuum distillation, to obtain 530 g of the 2-glycidyloxyethyl vinyl ether (A-37) (boiling point 65° C., 532 Pa). was added over 30 minutes stirred at 60° C. for 2 hour by washing with water The organic layer was extracted dried with magnesium sulfate, and condensed at reduced pressure to distill off the solvents The resulting liquid was purified by vacuum distillation

实验步骤: 1-Bromo-3-fluoro-5-(3-methoxypropoxy)benzene (4.0 g) was added to water (30.4 mL), and then thereto were added ethylene glycol monovinyl ether (6.8 mL), potassium carbonate (2.52 g), 1,3-bis(diphenylphosphino)propane (125 mg) and palladium acetate (34 mg), and the mixture was heated to stir at 90° C. for 22 hours. After cooling, thereto was added concentrated hydrochloric acid (7.2 mL), and the mixture was stirred at room temperature for 20 minutes. The reaction solution was extracted with ethyl acetate, washed with saturated saline, and then dried over magnesium sulfate. After concentrating under reduced pressure, the resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=20/1→2/1) to give 1-[3-fluoro-5-(3-methoxypropoxy)phenyl]ethanone [REx(19-2)] (1.03 g) as a yellow oil. the mixture was heated After cooling the mixture was stirred at room temperature for 20 minutes The reaction solution was extracted with ethyl acetate washed with saturated saline dried over magnesium sulfate After concentrating under reduced pressure the resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=20/1→2/1)
