Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Pyridine | HCID 1049 | — |
| Reactant | Benzoyl chloride | HCID 7412 | — |
| Reactant | 2-Amino-4-chloro-5-nitrophenol | HCID 3894848 | — |
| Product | Benzamide, N-(5-chloro-2-hydroxy-4-nitrophenyl)- | HCID 5483228 | 89% |
Reaction Steps
188 (1 mole) g of 2-amino-4-chloro-5-nitrophenol and 79 g (1 mole) of pyridine were added to 500 ml of N-dimethylacetamide, followed by dropping 140 g (1 mole) of benzoyl chloride at about 5° C. in about 30 minutes and agitating for further 30 minutes. The resulting crystals were filtered and washed with 500 ml of methanol to obtain 260 g (yield 89%) of an isomer of exemplified compound [IV]-(1) (2-benzamido-4-chloro-5-nitrophenol). From the melting point of below 250° C. and an IR spectrum (νC=O, 1654 cm-1), this compound was found to be 2-benzamide compound.
