Versuchsvorschrift
In a similar fashion an equal molar amount of 4-(2-chlorophenyl)-2-butanone, prepared from o-chlorobezaldehyde, (R)-1(3-methoxyphenyl)ethylamine and 1.25 equivalents titanium(IV) isopropoxide were mixed and the intermediate imine reduced with ethanolic sodium cyanoborohydride. Work-up and repetitive preparative thin-layer chromatography using 5% methanol in chloroform afforded (R,R)-N-[4-(2-chlorophenyl)-2-butyl]-1-(3-methoxyphenyl)ethylamine, 4T; m/z (rel. int.) 317 (M+, 3), 302 (16), 178 (62), 135 (100), 125 (15), 105 (10), 91 (6), 77 (8).
