반응 단계
To a solution of 2-bromo-5-hydroxybenzaldehyde (62; 5 g, 0.025 mol) in DMF (100 ml) was added (R)-4-(chloromethyl)-2,2-dimethyl-1,3-dioxolane (63; 4.87 g, 0.032 mol) and K2CO3 (7.0 g, 0.05 mol). The resulting reaction mixture was stirred at 150° C. for 10 h, cooled to room temperature, diluted with water, and then extracted with EtOAc. The combined organic layers were dried (Na2SO4) and concentrated under reduced pressure. The resulting residue was purified by chromatography (petroleum ether/EtOAc=10:1 to afford the desired product, namely (S)-2-bromo-5-((2,2-dimethyl-1,3-dioxolan-4-yl)methoxy)benzaldehyde 64 (4.1 g, 56%).
