Process for the production of a new basic ether. Ele; @enstand of the present patent is a process for the production of a new basic ether, namely 1.-phenoxy-2- \ -isopi-opylalrlino) -propane. - 1) This Ätlier is to be used as a pharmaceutical, but above all as an intermediate product for adjusting further derivatives.
The method forming the subject of the patent is characterized in that plan a compound, of the formula.

atoni, an alky1 resp. AryIsiilfoiiyloxy-Radi- 'aal.
According to the invention, for example, 1-1'lienoxy -? - an) inopropane can be reacted with an isoprol @@ -lha @ omenid.
It is preferable to work in a solvent such as. B. benzene, toluene, xylene, etc.
Furthermore, according to the invention, one can also proceed in such a way that 1-phenoxy-2-halopropane is reacted with isopropylamine.
In the case of the design variants mentioned, in the presence of a condensation or acid binding agent work. 13ierzu can be a tertiary amine such. B. Tri- äthylamin or the amine used in excess, or alkalis, z. B. alkali amides, alkaline solutions, salts sehwa cher acids with alkalis, etc., are used as condensation agents.
<I> Example 1: </I> 20 g of 1-phenoxy-2-chloropropane are heated to 180 C for 14 hours in a closed vessel with 60 cubic meters of a benzodic solution of 36 g of isopropylamine with the addition of 18 cm3 of triethylamine After cooling, water is added to the reaction mass, the benzene is separated off and extracted. with dilute hydrochloric acid the basic parts.
The acidic aqueous solution is made alkaline and the oil which separates out is taken up in ether. The ether solution is dried, the ether is evaporated and the residue is distilled in vacuo.
1-phenoxy-2-N-isopropyl aminopropane is obtained as a colorless oil which boils at 118 to 119 below 12 mm. The yield is 4 g, that is 1.7% of theory. The chlorohydrate of the base melts at 136-137. An equivalent weight determination shows that no tertiary base is formed.

Equivalent weight: <SEP> ago. <SEP> 193
<tb> found <SEP> 194, <SEP> 193 By increasing the reaction temperature to 180 to 200 C, a significant improvement in the yield can be achieved.
<I> Example, </I> 30 parts of 1-phenoxy-2-aminopropane in 180? - Benzene are heated to 150 to 160 in a closed vessel with the calculated amount of isopropyl bromide and triethylamine. The procedure is as indicated in Example 1, and 1-phenoxy-2-N-isopropylaminopropane is obtained with a bp "118 to 119o
