N,N-Dibutylaniline → 5-Butoxy-4-methyl-1,3-oxazole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | N,N-Dibutylaniline | HCID 61154 | — |
| Reactant | n-Butyl alpha-isocyanopropionate | HCID 11171108 | — |
| Product | 5-Butoxy-4-methyl-1,3-oxazole | HCID 9877440 | 98.7% |
Reaction Steps
Example 5 is repeated except that a mixture of 11.8% by weight of n-butyl α-isocyanopropionate and 88.2% by weight of N,N-dibutylaniline is added continuously via the inlet (A). 4-Methyl-5-n-butoxyoxazole is obtained in a yield of 98.7% via the top takeoff B and the amine via the sidestream takeoff D.
