Reaction Steps

2-Bromo-1,3-dimethyl-5-[3-(methylsulfonyl)propoxy]benzene (1.0 g), 3-formylphenylboronic acid (0.49 g, 1.05 eq), tripotassium phosphate (1.32 g, 2.0 eq), 10% Pd—C(PE) (0.1 g, 1.38 mol %), rac-BINAP (26.8 mg, 1.38 mol %), dimethyl sulfoxide (10 mL) and water (5 mL) were added. After nitrogen substitution, the mixture was stirred at 80° C. for 3 hr. The obtained reaction mixture was analyzed by high performance liquid chromatography to find the title compound (91.2% peak area).
