Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Dimethylformamide dimethyl acetal | HCID 78373 | — |
| Reactant | 1-(1H-Imidazol-1-yl)-3,3-dimethylbutan-2-one | HCID 12769453 | — |
| Product | HCID 54559550 | HCID 54559550 | 90.5% |
Reaction Steps
41.6 g (0.25 mol) of 3,3-dimethyl-1-(imidazol-1-yl)-butan-2-one and 35.7 g (0.3 mol) of dimethylformamide dimethyl acetal were heated under reflux for 5 hours. The excess acetal was then distilled off. The oil which remained crystallized on cooling. 50 g (90.5% of theory) of 4,4-dimethyl-1-dimethylamino-2-(imidazol-1-yl)-pent-1-en-3-one of melting point 45°-50° C. were obtained. ##STR16##
