Procedure

The title compound was prepared by the method of Example 6 (that is, using 2,2,6,6-tetramethylpiperidine as base instead of triethylamine) using 2,4-pentanedione instead of ethyl acetoacetate. The material prepared by this procedure was identical to that prepared by the method of Example 30, as indicated by the reverse phase chromatographic method described in Example 2.
