Preparation 14 4-Methoxybutyl 4-bromobenzenesulfonate To a solution of 4-methoxy-1-butanol (2.0 g, 19.2 mmol) in dichloromethane (20 mL) was added triethylamine (3.9 mL, 28.9 mmol) followed by 4-bromobenzenesulfonyl chloride (7.35 g, 28.9 mmol) and the reaction mixture was stirred overnight. Hydrochloric acid (20 mL of 2 N) was added and the aqueous phase washed with dichloromethane (2 x 10 mL). The combined organic layers were washed successively with aqueous saturated sodium hydrogencarbonate (20 mL) and then water(20 mL) and then dried over MgSO4and concentrated in vacuo.The product was obtained as a pale oil (6.10 g, 98%). NMR (CDCl3): 1.6 (m, 2H), 1.8 (m, 2H), 3.3 (s, 3H), 3.35 (m, 2H), 4.1 (m, 2H), 7.6-7.9 (m, 4H).
