Alcohol continued ethyl

If time permits, the procedure may be continued without allowing the mixture to stand overnight. If the drying of the alcohol and ethyl acetate is begun in the morning, however, this is a convenient point at which to interrupt the procedure. 

A solution of 140 g. (1 mole) of glycine ethyl ester hydrochloride 1 and 3 g. of sodium acetate in 150 ml. of water is added to the flask and cooled to 2° by means of an ice-salt bath. A cold solution of 80 g. (1.15 moles) of sodium nitrite in 100 ml. of water is added, and the mixture is stirred until the temperature has fallen to 0°. The temperature is maintained below 2°, and stirring is continued throughout all the following operations. To the cold mixture are added 80 ml. of cold, alcohol-free ethyl ether (Note 1) and 3 ml. of cold 10% sulfuric acid. After 5 minutes, the reaction mixture is blown over into the 1-1. separatory funnel by application of air pressure. The lower aqueous layer is quickly sucked back into the reaction flask. The ether layer is removed and immediately washed with 50 ml. of cold 10% sodium carbonate solution. This ether solution should be neutral to moist lilmus paper if not, the washing with sodium carbonate is repeated. The ether solution is finally dried over 10 g. of anhydrous sodium sulfate.

Ninety grams of finely powdered / -3-methoxy-4 5-methylene-dioxyphenylpropionamide were added to 1400 c.c. of an alkaline solution of sodium hypochlorite containing 77 grams of active chlorine (compare Graebe, Ben, 1902, 36, 2753), and the mixture was shaken continuously until the amide had completely dissolved, for which about two hours were necessary. The clear solution was then heated for a short time (fifteen minutes) on the boiling-water bath, when a dark-coloured oil separated, which was extracted with ether. The ethereal solution was washed with water, and subsequently shaken with dilute hydrochloric acid until the base was completely extracted. A small portion of this acid solution, when concentrated to a small volume, yielded crystalline hydrochloride, which was purified by recrystallisation from a mixture of absolute alcohol and ethyl acetate. It separated from this solvent in colourless needles, melting at 165° ...
