실험 절차

Triethylamine (8.67 g) (supplied from Wako Pure chemical Industries), 7.74 g of magnesium sulfate anhydrate and 4.55 g of benzaldehyde were added to a suspension of 7.79 g of methyl 2-aminohexanoate hydrochloride in 70 mL of dichloromethane, and stirred at room temperature overnight. The reaction suspension was filtrated, and the filtrate was concentrated. Then 280 mL of ether was added to the residue. The resulting suspension was filtrated and the filtrate was concentrated. Again 280 mL of ether was added to the residue, and the filtration and the concentration were repeated in the same manner, to yield 10.0 g of the title compound.
