Procedure
2-Isopropoxybenzyltriphenylphosphonium bromide was prepared from 2-isopropoxylbenzyl bromide according to the method used in Example 76, except that 1.3 equivalents of triphenylphosphine was used. 2-Isopropoxybenzyltriphenylphosphonium bromide was isolated as a white solid. Yield (11.2 g, 99%): 1H NMR (400 MHz, DMSO-d6) δ 7.86-7.89 (m, 3H), 7.70 (dt, J=8.0, 3.2 Hz, 6H), 7.54-7.59 (m, 6H), 7.23-7.28 (m, 1H), 6.91 (dt, J=7.6, 2.0 Hz, 1H), 6.88 (d, J=8.4 Hz, 1H), 6.74 (t, J=7.6 Hz, 1H), 4.87 (d, J=14.4 Hz, 2H), 4.29 (quint, J=6.0 Hz, 1H), 0.91 (d, J=6.0 Hz, 6H).
