実験手順

Dry toluene (150 ml), 25 ml oxalyl chloride (295), and a trace of DABCO (diaza-bicyclo[2.2.2]octane) were heated to 90°. Ten g of 2-furansulfonamide was added over a 15 minute period and the mixture was held at 95° for 2 hours. After filtering, the solvent was removed under vacuum to yield 2.1 g of an oil showing the characteristic isocyanate absorption in the infrared (2280 cm-1).
