الإجراء التجريبي

The title compound of Example 1 was treated with trifluoroacetic acid using the general procedure A to deprotect the BOC group. The resulting trifluoroacetic acid salt was coupled to Boc-N-Me-Ala-OH using the general procedure D to prepare the title compound of Example 2. 1H NMR (CDCl3): consistent with proposed structure.
