Procedure

15.1 gm of methyl anthranilate and 9.0 gm of β-tetronic acid were dissolved into 100 ml of ethanol, and 2 ml of concentrated hydrochloric acid was added, followed by stirring for 15 hours at room temperature. Deposited crystals were collected by filtration, washed with cold ethanol, and dried to obtain 19.2 gm of methyl N-(2,5-dihydro-5-oxo-2-furanyl)anthranilate.
