Procedure

Methyl (N-methyl-3-phenylanilino)acetate (4.33 g) was formylated as described in Example 1 by treatment with sodium hydride (0.94 g) and methyl formate (21.01 g) in DMF (50 ml) to give methyl 3-hydroxy-2-(N-methyl-3'-phenylanilino)propenoate (0.60 g) as a brown viscous liquid. Methylation with dimethyl sulphate (0.59 g) and potassium carbonate (0.62 g) in DMF (25 ml) for 5 hours afforded on work-up and HpLC (eluent petroleum ether--ether, 70:30) on silica gel a pure sample of the title compound (260 mg) as a yellow liquid.
