(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 (2 mL) by heating and benzenesulfonic acid (40 mg, 0.24 mmol), dissolved in tetrahydrofuran (4 mL), was added dropwise. Diethyl ether was added and the resulting oil was titurated. The solid was filtered and washed with diethyl ether to give a white solid that was stored in an exicator over blue gel: mp >250° C. Anal. Calcd. for C27H36N4O2×C6H6O3S×H2O: 63.4; H, 6.8; N, 9.0. Found: C, 63.1; H, 7.0; N, 8.7.
