Participants

Reaction Steps

In 30 mL of methanol, 0.2 g (0.50 mmol) of (E)-methyl 3-methoxy-2-(2-((4-(2-methoxyacetyl)-2,5-dimethylphenoxy)methyl)phenyl)acrylate obtained in Step 2 was reacted with 0.21 g (5 eq) of methoxyamine hydrochloride at room temperature for 15 hours with stirring. After completion of the reaction, the solvent was removed in a vacuum, and the residue was stirred in water (30 mL) and extracted twice with 30 mL of dichloromethane. The organic layer was dried over anhydrous magnesium sulfate and concentrated in a vacuum. Purification by silica gel chromatography afforded 0.1 g of (E)-methyl 3-methoxy-2-(2-((4-((Z)-2-methoxy-1-(methoxyimino)ethyl)2,5-dimethylphenoxy)methyl)phenyl)acrylate as a white solid (yield: 50%).
