Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Cesium carbonate | HCID 10796 | — |
| Reactant | alpha-Bromo-o-fluorotoluene | HCID 67968 | — |
| Reactant | Methyl 1-(4-hydroxyphenyl)-5-oxopyrrolidine-3-carboxylate | HCID 2883518 | — |
| Product | (RS)-1-[4-(2-fluoro-benzyloxy)-phenyl]-5-oxo-pyrrolidine-3-carboxylic acid methyl ester | HCID 68615230 | 82% |
Reaction Steps
In an analogous manner to that described in Example 13 a), the alkylation of the (RS)-1-(4-hydroxy-phenyl)-5-oxo-pyrrolidine-3-carboxylic acid methyl ester [Example 2 b)] with 2-fluorobenzyl-bromide using cesium carbonate as the base at RT yields (RS)-1-[4-(2-fluoro-benzyloxy)-phenyl]-5-oxo-pyrrolidine-3-carboxylic acid methyl ester as a light yellow solid (yield 82% of theory).
