YieldReaction ConditionsOperation in experiment
(b) 2-Methoxymethoxyphenylboronic Acid. In a manner similar to that of Example 1(a), starting with 19.00 g (8.7 mmol) of 2-methoxymethoxybromobenzene, 11.00 g (70%) of the expected product are obtained in the form of a white solid with a melting point of 63-66 C. 1H NMR (CDCl3) δ 3.51 (s, 3H), 5.31 (s, 2H), 6.21 (s, 2H), 7.07 (d, 1H, J=7.3 Hz), 7.14 (d, 1H, J=8.8 Hz), 7.43 (dt, 1H, J=8.6/1.9 Hz), 7.87 (dd, 1H, J=7.3/1.8 Hz).

YieldReaction ConditionsOperation in experiment
71% Under an argon atmosphere, apentane solution of tert-butyllithium (1.52 M, 14.4 mL, 21.9 mmol) was added dropwise to a solution of S1 (2.38 g, 11.0 mmol) in THF (30 mL) at -78 C. After stirring for 1 h at -78 C, trimethyl borate (1.84 mL, 16.5 mmol) was added as a neat liquid and the mixture was stirred for 1 h at -78 C. The reaction mixture was allowed to warmto room temperature and stirred for an additional 1 h. The mixture was quenched with saturatedaqueous NH4Cl and concentrated. The products were adjusted to pH 3 with acetic acid and themixture was extract with dichloromethane. The extract was washed successively with water and brine, dried over Na2SO4, and evaporated. The residue was washed with hexane and dried underreduced pressure to give 8a as a colorless powder (1.41 g, 71%). This compound was used for thenext reaction without further purification.
