Procedure

To a solution of 210 grams of stannous chloride dihydrate in 590 ml. of concentrated hydrochloric acid is added portionwise 25 grams of 3,5-dinitrobenzonitrile. The mixture is stirred for three hours at room temperature, then cooled to 0° in an ice-salt bath and a cold 50% sodium hydroxide solution added to the mixture until the mixture is strongly basic. During the addition the temperature is kept below 5° .
