In the same manner as in Reference Example 1, methyl 7-chloro-3-oxo-3,4-dihydro-2H-1,5-benzoxathiepine-4-carboxylate was reacted with 3-(4-phenylpiperazin-1-yl)propyl chloride to give methyl 7-chloro-3-oxo-4-[3-(4-phenylpiperazin-1-yl)propyl]3,4-dihydro-2H-1,5-benzoxathiepine-4-carboxylate. When converted to hydrochloride, white crystals were obtained, melting point 197°-199° C.
