실험 절차

To a refluxing mixture of 2-(1-methylethenyl)benzenesulfonamide (2.6 g, 12 mmol) and n-butylisocyanate (1.4 g, 14 mmol) in 20 ml xylenes plus a trace of DABCO (ca. 20 mg) was added liquified phosgene (1.2 ml, 16 mmol) dropwise at 139°. Refluxing was continued for 2 hours, and the solvent was removed in vacuo to give an oil. The infrared spectrum of the oil product exhibited a band at 2220 cm-1 indicating the title compound which was stored as a solution in methylene chloride.
