Versuchsvorschrift

To the THF (5.0 mL) solution of 4-[4-(2,2,4,6,7-pentamethyl-2,3-dihydro-1-benzofuran-5-yl)piperazin-1-yl]benzonitrile (180 mg, 0.479 mmol) synthesized in Example 90, lithium aluminum hydride (91 mg, 2.39 mmol) was slowly added under ice cooling, followed by stirring for 1.5 hours. To the reaction solution, sodium sulfate.10 hydrate (500 mg) was added. The temperature was raised to room temperature and the mixture was stirred for 16 hours. Undissolved residues were removed by filtration and the filtrate was concentrated under reduced pressure. To the resulting residue, hexane was added. The resulting solids were filtered to obtain the title compound 120 mg (yield 66%). Melting point was 156 to 158° C. (hexane-THF).
