Procedure: 1-(4-chlorophenyl)-2-methylpiperazine (300 mg, 1.4 mmol) was dissolved in methanol (3 ml), and the resulting solution was mixed with palladium carbon (150 mg) and stirred at a room temperature for 21 hours in an atmosphere of hydrogen. The reaction solution was filtered, and the thus obtained residue was thoroughly washed with ethanol. The washed solution and filtrate were combined, and the solvent was evaporated therefrom under a reduced pressure to obtain 260 mg of the title compound (1.4 mmol, 100% in yield). The reaction solution was filtered the thus obtained residue was thoroughly washed with ethanol the solvent was evaporated

Procedure: In the same manner as described in Example 1, N-(2-chloroethyl)morpholine is reacted with 1-phenyl-2-methylpiperazine. The trihydrochloride has a melting point 288°-290° (from methanol); Rf=0.63 (MeOH-conc. NH4OH 97:3); IR (nujol) νmax: 2420, 1500, 1405, 1265, 1060, 770, 695 cm-1 ; 1H-NMR (D2O; (CH3)3Si(CD2)2COONa): 1.05 (d, J=6 Hz; 3H; 2.70-4.20 (m; 19H); 7.47 (s; 5H).
