Reaction Steps

To 1 g (5.48 mmol) of (isochroman-1-yl)methyl chloride obtainable by Reference Example 1 was added 2 g (23.3 mmol) of piperazine, and the resulting mixture was heated at 100° to 120° C. for 10 hours. After being cooled, the mixture was basified with the addition of 10% sodium hydroxide and then extracted with chloroform. The extract was washed with water and then dried. The solvent was evaporated off. The residue was distilled under reduced pressure (150° C./15 mmHg) to give 0.9 g (74%) of the desired compound as an oily.
