Description

Patentirt im Deutschen Reiche vom 9. Juli 1897 ab.Patented in the German Empire on July 9, 1897.

Erhitzt man p-Phenetidin (34,6 kg) in alkoholischer Lösung während 10 Minuten mit 14,8 kg Orthoameisensa'ureester auf dem Wasserbade am Rückflufskühler und läfst das Reactionsproduct in verdünnte Natronlauge einlaufen, so scheidet sich ein OeI aus, welches nach kurzer Zeit erstarrt. Das Product wird mehrmals aus verdünntem Alkohol umkrystallisirt und schmilzt bei 1140; das Hydrochlorat schmilzt bei über 200°. Das Acetat ist in Wasser schwer löslich.If p-phenetidine (34.6 kg) is heated in alcoholic solution for 10 minutes with 14.8 kg of orthoformic acid ester on the water bath on the reflux condenser and the reaction product is run into dilute sodium hydroxide solution, an oil separates out, which after a short time stiffens. The product is several times recrystallized from dilute alcohol and melts at 114 0; the hydrochlorate melts at over 200 °. The acetate is sparingly soluble in water.

Für die Bereitung der Verbindung kann man auch direct Phenetidin und Orthoameisensäureester in neutraler Lösung erhitzen, jedoch ist die Ausbeute erheblich schlechter.Phenetidine and orthoformic acid ester can also be used for the preparation of the compound Heat in neutral solution, but the yield is considerably poorer.

Aus ρ-Anisidin und Orthoameisensäureester erhält man eine bei 119 ° schmelzende Verbindung: . ■■·■·.'·■'■■■■.A compound melting at 119 ° is obtained from ρ-anisidine and orthoformic acid ester: . ■■ · ■ ·. '· ■' ■■■■.

Merkwürdigerweise gelingt es nicht, eine ähnliche Verbindung zu bereiten aus Orthoameisensäureester und ρ - Amidophenolhydrochlorat.. :Strangely enough, it is not possible to prepare a similar compound from orthoformic acid ester and ρ - amidophenol hydrochlorate ..:

Die Verbindung hat die Eigenschaft, die Haut unempfindlich zu machen, und in geringen Dosen hindert sie die Seekrankheit.The compound has the property of making the skin insensitive, and to a small extent Doses she prevents the seasickness.
