Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Chlorine | HCID 24526 | — |
| Reactant | N-Methylacetoacetamide | HCID 88483 | — |
| Product | Butanamide, 2-chloro-N-methyl-3-oxo- | HCID 20065 | 97.4% |
Reaction Steps
Altogether, the aqueous phase was subjected to chlorination five times. A total of 492 parts by weight of N-methylacetoacetamide (MMAA) of 99.5% strength, and 283.5 parts by weight of chlorine were used, and altogether 588.6 parts by weight of 97.4% N-methyl-α-chloracetoacetamide (MMCAA) were obtained, that is, 96.8% of the theoretical yield, calculated on reacted MMAA.
