Procedure

The product from Example 145 and cyclopentylmagnesium bromide were processed as described in Example 146, except that additional cyclopentylmagnesium bromide was added after the reaction had stirred overnight (400 mol %) and after another four hours (600 mol %). The reaction mixture was allowed to stir for three additional days (16% yield).
