実験手順

(4-(2-[(5,6-Diphenyl-2-pyrazinyl)oxy]ethoxy)benzaldehyde (2.90 g) was dissolved in ethanol (30 mL), and sodium borohydride (615 mg) was added to the resultant solution under ice cooling. The mixture was stirred at room temperature for one hour. Subsequently, water was added to the reaction mixture, and the thus-formed organic matter was separated through extraction by use of methylene chloride, followed by washing sequentially by water and saturated saline. The washed product was dried over sodium sulfate anhydrate, and the residual solvent was removed through distillation under reduced pressure. The thus-yielded residue was crystallized from n-hexane, to thereby yield 2.69 g of the title compound as colorless crystals (yield 92.3%).
