Dibenzoylmethane → HCID 14155098, compound

Participants

Reaction Steps

A solution of 8.40 g (37.5 mmol) of dibenzoylmethane and 7.73 g (37.5 mmol) of 3-amino-5-benzylthio-1,2,4-triazole in 50 ml of glacial acetic acid was heated at reflux for 24 hours. Upon cooling to room temperature the solid which separated was collected by filtration and dried. The product was chromatographed on silica gel (HPLC) eluting with EtOAc-hexane (3:7, v/v) to afford 5.08 g (34%) of the desired product as a colorless solid, m.p. 122.5°-123.5° C. IR and 1H NMR spectra were in agreement with the assigned structure.
