Versuchsvorschrift

3-(1-Methoxyphenylsulfinyl)aniline (145 mg, 0.59 mmol) and pyridine-3-carboxaldehyde (63 mg, 0.59 mmol) were reacted in anhydrous methanol (3.0 ml), followed by treatment with sodium borohydride (44 mg, 1.17 mmol) as previously described (Intermediate 3). Silica gel chromatography (2 mm Chromatotron® plate, eluting with 20/1 ethyl acetate/hexanes) afforded N-(3-(2-methoxyphenylsulfinyl)phenyl)pyrid-3-ylmethylamine (162 mg, 82%) as an oil. 1H NMR(400 MHz): 3.77(3H,s), 4.35(2H,br s), 6.61(1H,m), 6.83(1H,d,J=8.0), 6.96(1H,br t), 7.01-7.04(1H,m), 7.11(1H,dt,J=7.8, 1.0), 7.18(1H,t,J=7.8), 7.21-7.28(1H,br s), 7.35-7.41(1H,m), 7.63(1H,br d), 7.82(2H,dd,J=7.8, 1.5), 8.40-8.80(2H,br s); MS(ESI)m/z 339.1([M+H]+,100)
