Procedure

Methyl-(E)-2 -(bromomethylphenyl)-2-methoxyiminoacetate as obtained in Example 27 (1) (250 mg), 3-chlorophenol (225 mg) and potassium carbonate (482 mg) were dissolved in DMF, and the resultant mixture was stirred at room temperature for 10 hours. A solution (677 mg) of methylamine in 30% methanol was added thereto, and stirring was continued for 10 hours. The reaction mixture was neutralized with dilute hydrochloric acid, extracted with diethyl ether. The solvent was dried and evaporated, and the residue was purified by silica gel column chromatography to give 265 mg of the objective compound.
