Procedure

This compound was prepared following the same method as for the preparation of compound 5c. The crude solid obtained showed the same NMR (CDCl3 /D2O) pattern as compound 5a, except for a peak at δ 3.5 for the OCH3 protons. It was sufficiently pure for the determination of its retention time following the HPLC method of analysis detailed in Example 37 below. No trials were made for its further crystallization or elemental analysis.
