The mixture was stirred under an atmosphere of hydrogen at ambient temperature for 2 hours. The catalyst was removed by filtration and the filtrate was concentrated to afford 4-(3-aminopropyl)benzylalcohol as a gum. In a similar manner to that described in Example 5, a reaction was carried out using 4-(3-aminopropyl)benzylalcohol, 4-pyridine-2-ylbenzoic acid (668 mg) and carbonyidiimidazole (650 mg) and the reaction mixture was treated to afford the desired compound (0.74 g) as colorless crystals.
