7-Hydroxychromanone → Methyl 3-(4-amino-2-methylphenyl)propanoate

Participants

Reaction Steps

A reaction was performed according to the synthesis method of Intermediate 1 by using Intermediate 7 (2.0 g) and 10% palladium hydroxide/activated carbon (1.5 g). The reaction mixture was filtered through Celite, and the solvent of the filtrate was evaporated under reduced pressure. The residue was purified by column chromatography (Yamazen, n-hexane:ethyl acetate=3:1), and the solvent was evaporated under reduced pressure by using a rotary evaporator to obtain the title compound (1.5 g) (the reaction was performed in THF solvent (20 ml) for 20 hours).
