Reaction Steps
The title compound was synthesized analogously to 83.8 (see experimental below), using a solution of saccharin (92 mg, 0.5 mmol) in DMF (anhydrous, 4 mL), NaH (60% dispersion in mineral oil, 21 mg, 0.52 mmol) and a solution of 3-phenoxypropyl bromide (130 mg, 0.6 mmol) in anhydrous DMF (1 mL). The crude obtained after workup was purified by flash column chromatography on silica gel (25% ethyl acetate-petroleum ether) to give 83.4 as a white solid (m p 83-86° C.) in 65% yield (130 mg). 1H NMR (500 MHz, CDCl3) δ 8.08 (dd, J=7.5 Hz, J=1.5 Hz, 1H), 7.95 (dd, J=7.5 Hz, J=1.5 Hz 1H), 7.89 (td, J=7.5 Hz, J=1.5 Hz, 1H), 7.85 (td, J=7.5 Hz, J=31.5 Hz, 1H), 7.30 (t, J=8.0 Hz, 2H), 6.97 (t, J=8.0 Hz, 1H), 6.93 (d, J=8.0 Hz, 2H), 4.11 (t, J=6.2 Hz, 2H), 4.04 (t, J=7.1 Hz, 2H), 2.36 (quintet, J=7.5 Hz, 2H).
