Abstract

1,191,535. Quinoline derivatives. GEVAERTAGFA N.V. 3 May, 1968 [24 May, 1967], No. 24191/67. Heading C2C. [Also in Division G2] 6 - Diethylamino - 1:2:3:4 - tetrahydroquinoline dihydrochloride is made by hydrogenation of 6-diethylamino-quinoline with H 2 / Ni and then treating the product with HCl. 1 - Ethyl - 6 - diethylamino - 1: 2: 3: 4 - tetrahydroquinoline dihydrochloride and 1-(4-sulphobutyl) - 6 - diethylamino - 1: 2: 3: 4 - tetrahyco. quinoline are made by heating 6-diethylamino- 1: 2: 3: 4 - tetrahydroquinoline with respectively (i) triethylphosphate and then HCI, and (ii) butane sultone.
