실험 절차
To 4-[1,3]dioxan-2-yl-butyric acid (2.55 g, 0.015 mol) in dichloromethane (200 ml) was added methylamine (2M in THF, 8.1 ml, 0.016 mol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (3.09 g, 0.016 mol) and hydroxybenzotriazole (2.16 g, 0.016 mol) and the mixture stirred at room temperature overnight. The organic layer was washed with saturated sodium bicarbonate solution (200 ml) and the aqueous layer extracted with dichloromethane (4×50 ml). The combined organics were dried (Na2SO4) and evaporated to give a colourless oil (3.2 g)
