Procedure
N-Methyl 3-(2,6-dimethoxybenzoyl)propionamide was demethylated with aluminium chloride in chlorobenzene to give N-methyl 3-(2-hydroxy-6-methoxybenzoyl)propionamide, m.p. 125° which may also be prepared from a by-product, N-methyl 3-(2,6-dihydroxybenzoyl)propionamide, by selective methylation with methyl iodide and potassium carbonate in acetone. (iii) By subjecting N-methyl 3-(2-hydroxy-6-methoxybenzoyl)-propionamide to a series of reactions similar to those described in Examples 1(i-ii) and 2(i-v), the title compound may be prepared.
