YieldReaction ConditionsOperation in experiment
100% With bromine; In acetonitrile; at -10 - 0℃; for 5h; Bromine (20.5 mL, 400 mmol) was added dropwise to a solution of the compound 61 that was obtained in Reference Example 25 (47.19 g, 100 mmol) in CH3CN (300 mL) at -10C. This solution was stirred at 0C for five hours and then a saturated aqueous Na2SO3 solution was added thereto. After extraction with ethyl acetate, the organic layer was washed with saturated saline, dried over Na2SO4, and concentrated under reduced pressure. The title compound 62 (2-bromo-3,4,5-tribenzyloxybenzoate methyl ester) (53.5 g, 100 mmol) was obtained in a quantitative yield. The NMR spectrum of compound 62 is shown in Table 30. Table 30 NMR spectrum of compound 62400 MHz 1H NMR (CDCl3) delta 7.45-7.24 (16H, m, Ar-H), 5.05 (6H, m, ArCH2O), 3.99 (3H, s, CO2CH3).
