実験手順

To a solution of (4-(5-bromo-2-chlorobenzyl)phenyl)methanol (intermediate AK) (1 g) in CH2Cl2 (10 mL), the solution of Dess-Martin periodinane (DMP) (1.22 g) CH2Cl2 (10 mL) was added dropwise. 0° C. The mixture was warmed to room temperature, and the reaction was monitored by TLC. After 1 h, CH2Cl2 was added to dilute the solution and 1 M NaOH was added to quench the reaction. The CH2Cl2 layer was separated and washed with aqueous NaHSO3 and brine, and dried over Na2SO4. The solvent was evaporated under reduced pressure, and the product was purified by column chromatography to obtain pure intermediate AL (0.62 g).
