実験手順

Alternatively, 3-cyano-2-(4-nitrophenylthio)-5-bromomethylpyridine is allowed to react in tetrahydrofuran with tri-(n-butyl)phosphine for ten hours. Following the addition of ether, the solid which forms is collected by filtration and washed with 1:1 tetrahydrofuran:ether to yield 8 3-cyano-2-(4-nitrophenylthio)pyridin-5-ylmethyl]-tri-(n-butyl)phosphonium bromide as a white solid; mp 175°-176° C.; NMR (CDCl3, 80 MHz) d 0.85-2.63(m, 27H), 4.76(d, 2H, J=15.4 Hz), 7.74(d, 2H, J=9.0 Hz), 8.26(d, 2H, J=9.0 Hz), 8.55 (brs, 1H), 8.79 (brs, 1H); IR (KBr) 2950, 2860, 2220, 1595, 1575, 1515, 1390, 1340, 1075 and 845 cm-1 ; HRMS 471.2116(M+ -HBr), Calc'd. for C25H34N3O2PS471.2109.
