Maleic Acid → 4-Methylpyridinium maleate
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Maleic Acid | HCID 444266 | — |
| Reactant | HCID 19871542 | HCID 19871542 | — |
| Product | 4-Methylpyridinium maleate | HCID 70360406 | 75.4% |
Reaction Steps
By following the same procedure as Example 6 except that a mixture of N-methylpyridinium methyl carbonate obtained in the 1st step of Example 4 and an equimolar amount of maleic acid were used, 4-methylpyridinium maleate was synthesized. By recrystallization, the desired product was obtained at 96.0% of the theoretical yield (yield of 75.4% to pyridine).
