(R)-N-[5-Methyl-8-(4-methylpiperazin-1-yl)-1,2,3,4-tetrahydro-2-naphthyl]-4-morpholinobenzamide (100 mg, 0.22 mmol) was dissolved in tetrahydrofuran (15 mL) and methanesulfonic acid (42 mg, 0.44 mmol), dissolved in tetrahydrofuran (5 mL), was added dropwise. The solvent was removed in vacuo to give a white solid that was recrystallized from acetone (5 mL) and then from a 15% H2O in acetone solution (7 mL). The crystals were filtered to give 37 mg (31% yield) of light yellow crystals that was stored in an exicator over blue gel: mp 250° C. (decom.). Anal. Calcd. for C27H36N4O2×CH4O3S×2H2O: C, 57.9; H, 7.6; N, 9.7. Found: C, 58.1; H, 7.4; N, 9.6.
