Reaction Steps

In analogy to the procedure described in example 1 f], [rac]-2-ethoxy-3-(4-hydroxy-2-methyl-phenyl)-propionic acid ethyl ester (example 34 b]) was reacted with 4-chloromethyl-5-methyl-2-(3,4,5-trimethoxy-phenyl)-oxazole (prepared from 3,4,5-trimethoxy-benzaldehyde and diacetyl monoxyme followed by treatment with POCl3 in analogy to the procedures described in examples 2 a] and b]) in the presence of cesium carbonate and potassium iodide to yield [rac]-2-ethoxy-3-{2-methyl-4-[5-methyl-2-(3,4,5-trimethoxy-phenyl)-oxazol-4-ylmethoxy]-phenyl}-propionic acid ethyl ester as yellow liquid.
