Procedure
2-Nitrophenethyl tosylate was prepared according to the general method as outlined in Preparation 1 starting from 2-nitrophenethyl alcohol (15 g, 89.7 mmol) and tosyl chloride (20.52 g, 110 mmol). The residue was triturated with hexanes and 26.44 g of off white crystals were collected. Yield 92%; 1H NMR (400 MHz, CDCl3) δ 7.93 (d, J=9.7 Hz, 1H), 7.91 (d, J=9.7 Hz, 2H), 7.64 (t, 1H), 7.39 (m, 2H), 7.24 (s, 2H), 4.32 (t, J=6 Hz, 2H), 3.24 (t, J=6 Hz, 2H), 2.41 (s, 3H).
