This compound was prepared according to the above method using benzaldehyde tosyl hydrazone (10.9 mmol) and a commercially available 1M solution of tetrabutylammonium hydroxide in methanol. The salt was isolated as an off-white solid. The compound appeared somewhat unstable at room temperature and was thus stored at −20° C., umax (KBr disc)/cm−1 2961, 1248, 1129, 1073, 1044; dH 0.89 (12H,t, J 7.5), 1.25-1.57 (16H,m), 2.28 (3H,s), 3.10-3.19 (8H,m), 6.95-7.35 (6H,m), 7.46 (2H,d, J 8.8), 7.82 (2H,d, J 8.8); dC (D2O) 13.7 (q), 19.7 (t), 21.3 (q), 24.0 (t), 58.5 (t), 124.7 (d), 125.5 (d), 127.0 (d), 127.9 (d), 128.4 (d), 138.6 (s), 138.8 (s), 138.9 (d), 143.6 (s); m/z (FAB) 758 ([M+H]++NBu4,100%), 516 (M++1, 15%).
