Reaction Steps
34.5 q of 5-benzyloxy-4-pyrone-2-carboxylic acid was suspended in 500 ml of concentrated hydrochloric acid and 250 ml of water and reacted for 1 hour at 80° C. The reaction solution was cooled with ice, and the formed crystal was taken out by filtration, washed with water and then dried, to obtain 16.6 g of 5-hydroxy-4-pyrone-2-carboxylic acid.
