Chlorobenzene → HCID 21398521, compound

Participants

Reaction Steps

A procedure was followed similar to that described in Example 1 but using 18 g. 1-(4-hydroxyphenyl)-2-(4-chlorophenyl)-1,2,3,4-tetrahydroquinoline, 3.8 g. sodium methoxide, 160 ml. chlorobenzene, 15 ml. dry methanol and 8.8 g. N-(2-chloroethyl) diethylamine. The crude material was chromatographed on 700 g. activated magnesium silicate (60-100 mesh) using benzene, benzene containing increasing amounts of ether, and ether as eluants and there was thus eluted with 7% - 50% ether in benzene and with ether 15 g. 1-{4-[2-(diethylamino)ethoxy]phenyl}-2-(4-chlorophenyl)-1,2,3,4-tetrahydroquinoline which was converted to the cyclohexanesulfamate salt; m.p. 161°-163° C. (isopropyl alcohol).
