The higher-melting sulfonyl cyanides which separate as solids should be dried when dissolved in a suitable solvent, e.g., benzene. p-Nitro-benzenesulfonyl cyanide is not readily extracted from the reaction mixture it is collected on a Buchner funnel, pressed as dry as possible, dissolved in benzene, washed with water, and dried over anhydrous calcium chloride.
