| Reactant | Acetamide | HCID 178 | — |
| Reactant | Rac-3-(2-bromo-pentanoyl)-benzoic acid methyl ester | HCID 87951238 | — |
| Product | 3-(2-Methyl-5-propyl-oxazol-4-yl)-benzoic acid methyl ester | HCID 69687570 | 36.1% |
Reaction Steps
A sample of rac-3-(2-bromo-pentanoyl)-benzoic acid methyl ester (1.50 g) and acetamide (0.89 g) were heated together to 130° C. for 15 h. The mixture was partitioned between AcOEt and brine, the organic layer was dried and evaporated and the residual oil was chromatographed on silica gel using AcOEt/hexane (1:3) as eluent to give 3-(2-methyl-5-propyl-oxazol-4-yl)-benzoic acid methyl ester (0.47 g) as a light-yellow oil.
