HRID 452605Notes

Reaction equation

[O:1]1[C:5]2[CH:6]=[CH:7][C:8]([C:10]([OH:12])=O)=[CH:9][C:4]=2[CH:3]=[CH:2]1.[C:13]([NH:16][NH2:17])(=[O:15])[CH3:14]>>[C:13]([NH:16][NH:17][C:10]([C:8]1[CH:7]=[CH:6][C:5]2[O:1][CH:2]=[CH:3][C:4]=2[CH:9]=1)=[O:12])(=[O:15])[CH3:14]

HCID 68664854N'-acetyl-1-benzofuran-5-carbohydrazideYield 85%

Procedure

In the same manner as in Reference Example 5 and using 1-benzofuran-5-carboxylic acid instead of benzothiazole-6-carboxylic acid and acetohydrazide instead of 3-[3-(trifluoromethyl)phenyl]propanohydrazide, the title compound (yield 85%) was obtained as colorless crystals.
