실험 절차

To a solution of 1.8 grams (0.0078 mole) of cyano(6-(3-fluorophenoxy)-2-pyridine methanol and 2.4 grams (0.0098 mole) of 2-isopropyl-2-(4-chlorophenyl)-acetic acid chloride in 50 milliliters of anhydrous ether was added 3 milliliters of triethylamine. A white precipitate separated out immediately. The reaction mixture was stirred at room temperature for one-half (1/2) hour. The mixture was successively washed with water, dilute hydrochloric acid, dilute sodium hydroxide, dilute sodium bicarbonate, dilute hydrochloric acid and water and thereafter dried over anhydrous magnesium sulfate and concentrated under vacuo to give 3.6 grams of 4-chloro-α-(1-methylethyl)benzeneacetic acid:cyano(6-(3-fluorophenoxy)-2-pyridinyl)methyl ester product as a viscous yellow oil having a refractive index of nD25 =1.5560. The structure of the product was confirmed by its nuclear magnetic resonance spectrum (NMR). In addition, upon analysis, the product was found to have carbon, hydrogen and nitrogen contents of 65.52, 4.74 and 6.18 percent, respectively, as compared with theoretical contents of 65.66, 4.59 and 6.38 percent, respectively, as calculated for the above-named compound (Compound No. 3).
