|---|---|---|---|
| Reactant | Trimethyl phosphonoacetate | HCID 80029 | — |
| Reactant | 3-Methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)cinnamaldehyde | HCID 53822879 | — |
| Product | methyl (E,E)-5-[3-methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2,4-pentadienoate | HCID 131721330 | — |
Reaction Steps
In substantially the same manner as in Reference Example 16, 3-methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)cinnamaldehyde was allowed to react with trimethyl phosphonoacetate to produce methyl (E,E)-5-[3-methoxy-4-(5-methyl-2-phenyl-4-oxazolylmethoxy)phenyl]-2,4-pentadienoate, which was recrystallized from ethyl acetate to give colorless prisms, m.p.166-167° C.
