反応手順
A solution of 24 parts of α-acetoxypropionaldehyde, 35.4 parts of acetoacetanilide and 2 parts of p-toluenesulfonic acid in 100 parts of benzene is kept for 3 hours at 40° C and then boiled under reflux for 1 hour. Adopting the isolation procedure described in Example 1 there is obtained 41.8 parts of 2,5-dimethylfuran-3-carboxanilide having a melting point of 92° to 93° C.
