Ammonia → 2-Benzyl-3-hydroxypropanoic acid

Participants

Reaction Steps

2-Benzylidene-3-hydroxypropionic acid (490.4 mg, 2.752 mmols) was dissolved in 7 ml of methanol, and 0.5 ml of 28% aqueous ammonia and 2 ml of water were added thereto. Then, 38 mg (water content 52.7%) of 5% palladium-carbon were added thereto, and catalytic reduction was conducted in a hydrogen atmosphere for 160 minutes. After the completion of the reaction, the reaction solution was filtered with Celite to remove the palladium-carbon. The resulting filtrate was subjected to the HPLC analysis. As a result, the filtrate contained 461 mg (2.558 mmols) of the above title compound (yield 93.0%).
