81% With hydrogen bromide at 100℃; for 2h;
78% With sulfuric acid; sodium bromide In water for 4.5h; Reflux; 11 1,4-Bis(3-bromopropyl)benzene (C4) An emulsion of 1,4-bis(3-hydroxypropyl)benzene (9.0 g, 46.3 mmol) and sodium bromide (24.0 g, 0.23 mol) in deionized water (25 mL) was heated to reflux, while concentrated sulfuric acid (17 mL) was added dropwise over 1 h. After the addition, heating under reflux was continued for additional 3.5 h. The solution was cooled to room temperature, diluted with water (40 mL), and extracted with CH2Cl2 (2*150 mL). The combined organic layers were washed with saturated solution of NaHCO3 (100 mL), saturated NaCl solution (100 mL) and dried over MgSO4. The solvent was evaporated and the residue was purified by column chromatography (silica gel, EtOAc:hexanes, 1:40) to yield 1,4-bis(3-bromopropyl)benzene (11.6 g, 78%) as a colorless oil. 1H NMR (CDCl3): δ=7.15 (s, 4 H), 3.41 (t, J=6.6 Hz, 4 H), 2.77 (t, J=7.1 Hz, 4 H), 2.18 (m, 4 H). 13C NMR (CDCl3): δ=138.3, 128.7, 34.2, 33.4, 33.3. This known compound was prepared by a method different from the one described in Matsuoka, T., Negi, T., Otsubo, T., Sakata, Y., Misumi, S. Bull. Chem. Soc., Japan, 1972, 45, 1825-1833 and Ruzicka, L.; Buijs, J. B.; Stoll, M. Helv. Chim. Acta 1932, 15, 1220.

After cooling, to the solution was added dropwise a mixture of 3.2 g of 1,4-bis(3-bromopropyl)benzene and diethyl malonate over 5 minutes, and the mixture was refluxed for 40 minutes to obtain a white suspension. After cooling and addition of 21 ml of ice water, the mixture was adjusted to pH 7.0 with 1N hydrochloric acid, and ethanol was removed under a reduced pressure to obtain an aqueous layer, which was then twice extracted with 100 ml of benzene each time. The extract was washed with a saturated sodium chloride aqueous solution, dried over magnesium sulfate and evaporated under a reduced pressure to remove the solvent, and then to remove any unreacted diethyl malonate under a reduced pressure at 140° C. to obtain 4.74 g of the title compound as a colorless liquid. 1 H--NMR (CDCl3, δ ppm): 1.25 (12H, t, J=7.1 Hz), 1.5-1.7 (4H, m), 1.8-2.0 (4H, m), 2.60 (4H, t, J=7.7 Hz), 3.33 (2H, t, J=7.4 Hz), 4.18 (8H, q, J=7.1 Hz), 7.07 (4H, s).

After 1 h, a solution of 1,4-bis(3-bromopropyl)benzene (11.6 g, 36.3 mmol) in anhydrous THF (70 mL) was added dropwise, followed by the addition of DMPU (20 mL). The reaction mixture was allowed to warm to room temperature overnight, then cooled with an ice-bath, and hydrolyzed with saturated NH4Cl solution (100 mL). Water (100 mL) was added and the layers were separated. The aqueous layer was extracted with ethyl acetate (2*50 mL). The combined organic layers were washed with saturated NaCl solution (100 mL), dried with MgSO4, and concentrated in vacuum. The residue was purified by column chromatography on silica gel (EtOAc:hexanes, 1:10) to give 1,4-bis(4-ethoxycarboxy-4-methylpentyl)benzene (13.3 g, 94%) as a colorless oil. 1H NMR (CDCl3): δ=7.09 (s, 4 H), 4.11 (q, J=7.1 Hz, 4 H), 2.57 (m, 4 H), 1.57 (m, 8 H), 1.24 (t, J=7.1 Hz, 6 H), 1.47 (s, 12 H). 13C NMR (CDCl3): δ=177.9, 139.6, 128.2, 60.1, 42.0, 40.2, 35.8, 26.8, 25.1, 14.2.
