Reaction Steps

A 1 liter Parr autoclave was charged with 221 g. (1 mole) -dichlorophenyl)- of methyl 3,5-dichlorosalicylate and 140 g. (8 moles) of anhydrous ammonia. The mixture was stirred at 25° C for 24 hours. After venting excess ammonia, the product was ground to a fine powder and triturated with boiling chloroform. The mixture was filtered while hot and the residue weighed 153 g. Analysis by infrared, gas chromatography, and nuclear magnetic resonance confirmed that the product was 3,5-dichlorosalicylamide.
