Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | Ethyl propiolate | HCID 12182 | — |
| Reactant | N-formylsarcosine | HCID 11789184 | — |
| Product | Ethyl 1-methyl-1H-pyrrole-3-carboxylate | HCID 11062584 | 71.3% |
Reaction Steps
Using 117.1 g (1 mol) of N-formylsarcosine, 98.1 g (1 mol) of ethyl propiolate and 638 ml of acetic anhydride, a reaction and post treatment were conducted in a similar manner as in Referential Example 1. The resulting brown oil was distilled under reduced pressure and a 103°-104° C. fraction was collected under 4 mmHg, whereby 109.19 g of the title compound were obtained (yield: 71.3%).
