By the reactions in the same manner as in Example 3 using (S)-4-glycidyloxybenzo(b)furan-2-yl methyl ketone (0.52 g) obtained in Starting Material Synthesis Example 71 and 4-(naphthalen-2-yl)piperidine (0.47 g), (S)-4-(2-hydroxy-3-(4-naphthalen-2-yl)piperidino)propyloxy)benzo(b)furan-2-yl methyl ketone (0.87 g) was obtained as a brown oil. This was dissolved in ethyl acetate and maleic acid (0.22 g) was added. The precipitated crystals were recrystallized from a mixed solvent of isopropanol-ethyl acetate to give the title compound (0.76 g) as pale-yellow crystals, melting point 153–155° C.
