Hydrochloric Acid → n-Propyl ferulate

참여 물질

반응 단계

Ferulic acid (4.85 g) and then n-propyl alcohol (50 ml) containing hydrogen chloride (4%) were placed in an egg-plant type flask (200 ml), and heated under reflux overnight. The disappearance of the starting material was confirmed by thin layer chromatography (TLC: n-hexane/ethyl acetate=2/1), then the solvent was evaporated under reduced pressure by a rotary evaporator. Benzene was added to the residue, and then, the solvent was again evaporated by a rotary evaporator to obtain the crude product. The resulting crude product was separated and purified by silica gel column chromatography (diameter=5.5×7.0 cm; 60 g; n-hexane/ethyl acetate=2/1) to obtain the above-identified compound (5.48 g, 91.6%) as colorless oil.
