実験手順

A solution of Ethyl 2-(3-hydroxyphenyl)acetate (11 g, 61 mmol) in THF (100 mL) was added NaH (2.93 g, 73.3 mmol) and MOM-Cl) 5.94 g, 73.3 mmol) at 0° C. The reaction mixture was stirred for 16 hrs at 0° C. then warmed to room temperature. The reaction mixture was diluted with H2O (200 mL) and extracted with EtOAc. The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using EtOAc:hexanes (1:10) as eluant.
