Versuchsvorschrift

To a solution of 400 mg of methyl 5-(4-benzylpiperazin-1-yl)-2-methoxymethoxybenzoate (1.1 mmol) in 1,4-dioxane (20 mL) was added a solution of 4 N hydrogen chloride in 1,4-dioxane (4 mL, 16 mmol), and the resulting solution was stirred for 2 hours at 100° C. The resulting reaction solution was subjected to distillation under reduced pressure to obtain a residue. This residue was purified by silica gel column chromatography (dichloromethane:methanol=30:1), to thereby yield 353 mg of the title compound.
