YieldReaction ConditionsOperation in experiment
55% With phosphorus tribromide; at 20℃;Heating / reflux;Product distribution / selectivity; 6.2 EXAMPLES OF ILLUSTRATIVE COMPOUNDS OF THE INVENTION; Bis (3-bromopropyl) ether (104).; Under N2-atmosphere, phosphorus tribromide (7.2 mL, 20.5 g, 75.8 mmol) was added dropwise over 1 h to 103 (Buchanan, G. W. et al. Can. J Chem. 2000, 78, 316-321) (10.14 g, 75.6 mmol), causing self-heating to reflux. The reaction mixture was stirred overnight at room temperature, then distilled in vacuo to give an oil. This oil was dissolved in CH2C12 (100 mL), washed with water (100 mL), dried over Na2SO4, and concentrated in vacuo, affording 104 (10.9 g, 55 %) as a clear, colorless oil. Bp 68-70 C/0. 2 mmHg. 1H NMR (CDC13) : No. 3.56 (t, 4 H, J= 5.8), 3.51 (t, 4 H, J= 6.4), 2.10 (m, 4 H). 13C NMR (CDC13 = 77. 00 ppm) : 6 68. 17,32. 68,30. 59.
34% With phosphorus tribromide; at 20 - 90℃; To a flask containing compound 2 (11 g, 82.0 mmol), PBr3 (55 mL) was added slowly drop wise and the mixture stirred for 0.5 hours at ambient temperature followed by heating to 900C. After being stirred for 3 hours at this temperature the reaction mixture was quenched with ice (500 g) slowly, stirred continuously for 10 minutes and extracted with CH2Cl2 (2 X 700 mL). The organic layer was dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give compound 3 as a pale yellow liquid (7.24 g). Yield: 34%. 1HNMR (400 MHz, CDCl3): δ (ppm): 3.70-3.55 (t, 4H), 3.60-3.35 (t, 4H), 2.15-1.95 (m, 4H).

47% With potassium carbonate; In N-methyl-acetamide; acetone; EXAMPLE 56 Preparation of [4-acetyl-3-[3-(3-bromopropoxy)propoxy]-2-propylphenoxy]acetic acid ethyl ester A mixture of 2.5 g (0.0089 mole) of (4-acetyl-3-hydroxy-2-propylphenoxy)acetic acid ethyl ester, 11.6 g (0.045 mole) of 3,3'-dibromodipropyl ether, 1.0 g (0.0072 mole) of potassium carbonate in 50 ml of anhydrous acetone and 25 ml of anhydrous dimethylformamide was stirred at reflux for 66 hours. Additional 1.0 g portions of potassium carbonate were added after 6,18,26 and 42 hours. The reaction mixture was filtered and the filtrate was concentrated in vacuo to yield an oil which was chromatographed on 125 g of silica gel. Elution with 10% ethyl acetate-toluene gave 1.9 g (47% yield) of [4-acetyl-3-[3-(3-bromopropoxy)propoxy]-2-propylphenoxy]acetic acid ethyl ester as an oil.
