Reaction Steps

In a manner analogous to that above, the reaction of p-aminobenzoic acid (671 mg; 4.90 mmol), 1-(5-bromo-3-oxapentyl) methanethiosulfonate (1.29 g, 4.9 mmol) and CsCl (1.63 g, 5 mmol) yielded 7-(4-aminophenyl)-7-oxo-3,6-dioxaheptyl methanethiosulfonate (230 mg). 1H NMR (500 MHz, (CD3)2SO) δ 7.62 (d, J=8.7 Hz, 2H), 6.55 (d, J=8.7 Hz, 2H), 5.95 (s, br., 2H), 4.27 (t, J=4.7 Hz, 2H), 3.77 (t, J=6.0 Hz, 2H), 3.73 (t, J=4.7 Hz, 2H), 3.50 (s, 3H), 3.39 (t, J=6.0 Hz, 2H).
