실험 절차

To a solution of ethyl (1-methylethyl)carbamate (13.1 g, 0.1 mol) in 100 mlmethylene chloride cooled to 0° C. was added sulfur dichloride (11.3g, 0.11 mol) in one portion. While maintaining the temperature of the mixture at 0° C., pyridine (8.7 g, 0.11 mol) was added dropwise over eleven minutes. After complete addition of the pyridine the temperature was allowed to rise to room temperature and stirring was continued for additional 1.5 hours. The mixture was let stand overnight. Methylene chloride was evaporated under vacuum and 100 ml hexane was added. Filteration of the pyridine hydrochloride and evaporation of hexaneresulted in an orange oil which was distilled in a Kugelrohr apparatus to give 12.5 g of the title compound Bp: 64°-80° (bath temperature) at 1.4 mm Hg.
