Procedure
2-[(4-Pyridin-2-ylpiperazin-1-yl)methyl]-1H-benzimidazole (4.00 g, 13.6 mmol) in methanol (20 mL) and H2O (20 mL) was treated with (L) tartaric acid (4.09 g, 27.2 mmol). The resulting solid was filtered, washed with methanol (10 mL), and dried under reduced pressure to provide the title compound as a solid. Elemental analysis calc'd for C25H31N5O12: C, 50.59; H, 5.26; N, 11.80; O, 32.35. Found: C, 50.48; H 5.27; N, 11.78; O, 32.41. DSC: sharp endotherm at 206° C.
