**1,3-Dimethoxy-5-nonylbenzene (9)**

Compound **9** was prepared as described for compound **6** using a solution of **5** (792 mg, 3.00 mmol) in EtOH (30 mL) and 10% Pd/C (83 mg) to give **9** in 93% yield. 1H NMR (500 MHz, CDCl3): δ 6.38 (d, 2H, aromatic, J = 2.0 Hz), 6.33 (t, 1H, aromatic, J = 2.0 Hz), 3.81 (s, 6H, OC*H*3), 2.58 (t, 2H, CH2, *J* = 8.0 Hz), 1.64 (m, 2H, CH2), 1.35–1.30 (m, 12H, CH2), and 0.92 (t, 3H, CH3, J = 7.0 Hz).

#### **1,3-Dihydroxy-5-propylbenzene (10)**

A stirring solution of **6** (200 mg, 1.11 mmol) in CH2Cl2 was cooled to −10 ◦C for 30 min. To this cold reaction solution, BBr3 (1 M solution in CH2Cl2, 2.78 mL, 2.78 mmol) was added dropwise. After the addition, the mixture was allowed to warm up to room temperature and stirred for an additional 24 h. The mixture was cooled to 0 ◦C and quenched with saturated NaHCO3 and stirred for an additional 30 min at room temperature. The aqueous layer was extracted with CH2Cl2 (2 × 25 mL), combined organic layers were dried over MgSO4, filtered, and evaporated. Purification on a silica gel column by using CH2Cl2:MeOH (98:2) as an eluent gave 79% yield of **10 [27]**. 1H NMR (500 MHz, CDCl3): δ 6.28 (d, *J* = 2.0 Hz, 2H, aromatic), 6.21 (S, 1H, aromatic), 2.47 (q, 2H, CH2, *J* = 9.0 Hz), 1.59 (q, 2H, CH2, J = 8.0 Hz), and 0.93 (t, 3H, CH3, J = 7.5 Hz).

#### **1,3-Dihydroxy-5-butylbenzene (11)**

Compound **11** was prepared as described for **10** using compound **7** (0.5 g, 2.58 mmol) and BBr3 (1 M solution in CH2Cl2, 5.16 mL, 5.16 mmol) to give compound **11** in 68% yield [28,29]. 1H NMR (500 MHz, CDCl3): δ 6.28 (s, 2H, aromatic), 6.20 (d, 1H, aromatic, J = 2.0 Hz), 4.89 (bs, 2H, OH), 2.60–2.40 (m, 2H, CH2), 1.63–1.10 (m, 4H, CH2), and 0.92 (t, 3H, CH3, J = 7.0 Hz).
