Aus dem Filtrat wird das N-(a-Naphthoyl)-durylsulfanamid mit Essig säure ausgefällt und durch Umkri.stallisieren aus Alkohol gereinigt.
Statt unter Zuhilfenahme eines Konden sationsmittels, kann die Reaktion auch in Gegenwart eines säurebindenden Mittels, wie z. B. von Pyridin oder Dimethylauilin, oder in Gegenwart eines Katalysators, wie z. B. von Kupferpulver, ausgeführt werden.

<I> Example <SEP> 1: </I>
<tb> \ 31.3 <SEP> parts of <SEP> Durylsulfonamide <SEP> are <SEP> in
<tb> 1M <SEP> share <SEP> nitrobenzene <SEP> suspended <SEP> and <SEP> with;
<tb> 1.9 <SEP> parts <SEP> aluminum chloride <SEP> and <SEP> 19 <SEP> parts
<tb> a-naphthoic acid chloride <SEP> added. <SEP> The <SEP> Ge nW = eh <SEP> is heated <SEP> 2 <SEP> hours <SEP> to <SEP> 50 <SEP> and then the solvent is a.bdestil'liert with water vapor . The residue is taken up in soda solution, treated with animal charcoal and filtered. The N- (a-naphthoyl) -durylsulfanamide is precipitated from the filtrate with acetic acid and purified by recrystallizing from alcohol.
Instead of using a condensation agent, the reaction can also be carried out in the presence of an acid-binding agent, such as. B. of pyridine or Dimethylauilin, or in the presence of a catalyst, such as. B. of copper powder.
Instead of a halide, the free α-naphthoic acid can also be used in the presence of a condensation agent such as phosphorus pentoxide or phosphorus pentoxide.
Example 2: 28.6 parts of α-naphthoic acid amide are dissolved in 200 parts of absolute xylene. Then 8 parts of sodium amide are added and the mixture is heated until the ammonia development stops. After cooling, add 46,
4 parts of Duiylsulfoehlorid in 100 parts of xylene and heated for several hours under direct flow. After the reaction has ended, the xylene is distilled off in the Valzuum. The residue is taken up in bicarbonate solution, treated with animal charcoal, and filtered.
and precipitated by acidification. The N- (a-Naphtlioyl) -durylsulfona.mid is recrystallized from dilute alcohol and thus obtained completely pure.
