1-(1-Hydroxy-2-propyl)-2-triphenylmethylpiperazine (1.69 g) obtained in step 2 was dissolved in ethanol (20 ml), and a 4 mol/l hydrogen chloride solution in ethyl acetate (10 ml) was dropwise added thereto. The mixture was stirred at room temperature for 10 minutes. The solvent was distilled off under reduced pressure, the residue was suspended in ethyl ether, and the precipitated crystals were collected by filtration to give Compound L (840 mg, 89%).
