With potassium carbonate; In DMF (N,N-dimethyl-formamide); at 90 - 130℃; for 13h;
10.0 g of resorcin, 87.8 g of potassium carbonate, and 54 ML of isopropyl iodide were suspended in 100 ML of N,N-dimethylformamide, and this suspension was stirred for 10 hours at 90 to 110C. After the reaction mixture was filtered out, 43.9 g of potassium carbonate and 27 ML of isopropyl iodide were added to the filtrate, and this mixture was stirred for 3 hours at 120 to 130C. The reaction mixture was added to a mixture of ethyl acetate and water, and adjusted to PH 2 with 6M hydrochloric acid, and then the organic phase was separated therefrom.. After the resultant organic phase was washed with water and a saturated sodium chloride solution successively, the washed phase was dried over anhydrous magnesium sulfate, and the solvent was distilled out under reduced pressure. The resultant residue was purified by silica gel column chromatography [eluent; hexane:ethyl acetate=10:1] to yield 6.68 g of 1,3-diisopropoxybenzene as light brown oil. NMR(90MHz,CDCl3) delta value: 1.32(12H,d,J=6.1Hz), 4.30-4.72(2H,m), 6.42-6.51(3H,m), 7.03-7.23(1H,m)
at 10 Potassium carbonate (138g, 1.0mol) was added to compound 1 (55.0g, 0.5mol) in THFSolution (a 500 mL), and the mixture was stirred at 10 2 hours. At 10 will isopropyl iodide(162g, 1.0mol) added thereto. The temperature was raised to 70 deg.] C, the mixture was stirred for 14 hours. PassThe reaction solution was filtered, and the filtrate was concentrated. By using petroleum ether as eluent, concentrate purified by silica gel columnThereof, whereby the compound 2.

Operation in experiment
5.12 g of 4-isobutoxy-3-(3-ethoxy-3-oxopropyl)benzoic acid was dissolved in 51 ML of methylene chloride, and after the consecutive addition thereto of 1.8 ML of oxalyl chloride and 20 muL of N,N-dimethylformamide at room temperature, the resultant mixture was stirred for one hour at room temperature.. Then, 4.64 g of aluminum chloride and 3.30 g of <strong>[79128-08-8]1,3-diisopropoxybenzene</strong> were successively added to the reaction mixture at temperatures of -30 to -20C, followed by raising the temperature to 5C, where the mixture was stirred for one hour.. This reaction mixture was added to ice water for the separation of the organic phase therefrom.. After the resultant organic phase was washed with water and a saturated sodium chloride solution successively, the washed phase was dried over anhydrous magnesium sulfate and the solvent was distilled out thereof under reduced pressure.. The resultant residue was purified by silica gel column chromatography [eluent; hexane:ethyl acetate=5:1] to yield 5.05 g of ethyl 3-[5-(2,4-diisopropoxybenzoyl)-2-isobutoxyphenyl] propanoate as light yellow oil. NMR(90MHz,CDCl3) delta value: 1.06(6H,d,J=6.6Hz), 1.10(6H,d,J=6.1Hz), 1.23(3H,t,J=7.1Hz), 1.38(6H,d,J=6.1Hz), 1.91-2.38(1H,m), 2.47-2.69(2H,m), 2.87-3.07(2H,m), 3.80(2H,d,J=6.4Hz), 4.00-4.81(4H,m), 6.46-6.58(2H,m), 6.79(1H,d,J=9.3Hz), 7.33(1H,d,J=8.6Hz), 7.58-7.71(2H,m)
