note
-
The mother solution was concentrated under reduced pressure, and the residue was dissolved in hot MeOH. The solution was seeded with optically pure diastereopure 3 (ca. 20 mg), which was obtained by preparative HPLC (ODS) using MeOH as the eluent. It was kept overnight at room temperature to give 4.5 g of diastereomer 3 as colorless plates.
