The racemic mixture containing the (R)-enantiomer BAY X 1005 (IV) can be prepared according to the following scheme: 4-Hydroxyphenylacetic acid methyl ester (I) is coupled with 2-chloromethylquinoline and potassium carbonate in DMF. The resulting product (II) is alkylated with cyclopentylbromide and sodium hydride in DMF to give product (III). Final saponification is undertaken with sodium hydroxide in methanol leading to the racemic carboxylic acid (IV).
