실험 절차
Potassium hydroxide (56 g) was added to a suspension of cysteamine, hydrochloride (56.6 g) in absolute ethanol (300 ml) followed by dropwise addition of ethyl 2-bromohexanoate (111.5 g). When the exothermic reaction ceased, the mixture was refluxed for 3 hours and filtered. Concentration of the filtrate in vacuo gave the title compound as a viscous oil which was used in the next step without purification.
