Procedure
In analogy to the procedure described in example 44, rac-2-but-3-enyloxy-3-(1H-indol-5-yl)-propionic acid methyl ester (preparation 9) was reacted with 4-chloromethyl-5-methyl-2-o-tolyl-oxazole to give rac-2-but-3-enyloxy-3-[1-(5-methyl-2-o-tolyl-oxazol-4-ylmethyl)-1H-indol-5-yl]-propionic acid as light brown solid.
