Reaction Steps

The title compound was prepared using a procedure similar to that described in Example 5, except that ethyl 2-(4-fluorobenzyl)-8-hydroxy-1-oxo-1,2,3,4-tetrahydropyrrolo[1,2-α]pyrazine-7-carboxylate was substituted with ethyl 2-(3,4-difluorobenzyl)-8-hydroxy-1-oxo-1,2,3,4-tetrahydropyrrolo[1,2-α]pyrazine-7-carboxylate (Example 12).
