実験手順

A mixture of 4-((1R,2S)-2-{2-[2,6-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]ethylamino}-1-hydroxypropyl)phenol (0.02 g), 4-bromo-3-methylbenzoic acid (0.020 g), tetrakis(triphenylphosphine)palladium (0.0027 g), cesium fluoride (0.041 g), 1,4-dioxane (0.75 mL), ethanol (0.25 mL) and water (0.15 mL) was stirred at 100° C. overnight. After being cooled to room temperature, the reaction mixture was diluted with tetrahydrofuran (2.5 mL). The crude product was purified by SCX ion exchange column chromatography (Argonaut 1 g, preconditioning: tetrahydrofuran, washing solvent:tetrahydrofuran, eluent:2 mol/L ammonia in methanol), followed by reverse phase column chromatography (Shiseido Capcell Pak C18 ODS, 5 μm, 120 Å, 20×50 mm, linear gradient 0.1% aqueous formic acid/acetonitrile=90/10-60/40) to afford the title compound (0.0046 g) as a white amorphous. The structure and physical data were shown in table 1.
