5-Amino-2-chlorobenzoic acid → HCID 1252891, compound

Participants

Reaction Steps

To a suspension of 5-amino-2-chlorobenzoic acid (13.7 g, 79.85 mmol, 1.00 equiv) in tetrahydrofuran (100 mL) was added furan-2-carbonyl chloride (11.5 g, 88.10 mmol, 1.10 equiv) in a bath of ice and stirred overnight at room temperature. The resulting mixture was concentrated under vacuum and diluted with DCM. The solid was collected by filtration to give 17 g (80%) of 2-chloro-5-(furan-2-amido)benzoic acid as a gray solid.
