Hydrochloric Acid → HCID 15669330, compound

Participants

Reaction Steps

To a solution of 5-ethyl-2-furansulfonamide (4.5 g, 25.7 mmole) in 40 ml of acetone was added aqueous sodium hydroxide (25.7 ml of 1N, 25.7 mmole) followed by a solution of 4-chlorophenylisocyanate (3.9 g, 25.7 mmole) dissolved in 40 ml of acetone. The reaction was stirred at room temperature overnight and filtered through a plug of celite. The filtrate was acidified with hydrochloric acid (25.7 ml of 1N, 25.7 mmole) and the resulting precipitate filtered to produce 8.3 g of solid.
