PROCEDURE

实验过程

To 4-nitrobenzenesulfonamide (2.1 grams, 0.01 mole) in 100 milliliters dry toluene was added 1.2 grams (0.012 mole) methoxycarbonyl isocyanate. Three drops of pyridine were added. The mixture was refluxed for four hours. After cooling the precipitate was filtered off and washed with toluene. The solid material was dried. There was obtained 2.4 grams of the title compound, m.p. 150°-158° C.
