Reaktionsschritte

2-Chloro-4-hydroxy-benzaldehyde obtained in Step A was dissolved in CH3CN (20 mL). After Cs2CO3(8.7 g, 0.027 mol) was added thereto, benzyl bromide (1.5 mL, 0.013 mol) was added thereto, and the mixture was stirred at room temperature for 2 hours. After the termination of the reaction, the reactant was filtered by using celite, concentrated under reduced pressure, and purified by column chromatography (eluent, EtOAc/Hex=1/5) to obtain the title compound (1.89 g, 59%).
