The title compound was prepared as described for Example 24 from 1 equivalent of [3-(pyridin-2-yloxy)propyl]amine, 2-tert-Butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide and 1 equivalent TEA with a reaction time of 30 mins. The residue was purified by silica gel column chromatography (Horizons Biotage) using 5:1 petroleum ether 40-60° C. in EtOAc as eluent to give the title compound (0.178 g, 65%) as a solid. 1H NMR (500 MHz CDCl3): δ 8.17 (dd, 1H), 7.62-7.57 (m, 1H), 7.54-7.48 (m, 2H), 7.45-7.40 (m, 3H), 6.91-6.88 (m, 1H), 6.74 (d, 1H), 6.00 (t, 1H), 4.28 (t, 2H), 3.04 (q, 2H), 1.83 (quintet, 2H), 1.75 (s, 9H); 13C NMR (125 MHz CDCl3): δ 163.8, 159.9, 147.0, 138.9, 135.5, 131.8, 129.7, 128.8, 125.4, 117.3, 111.5, 106.9, 63.6, 61.6, 42.0, 28.9, 27.9; Mass Spectrum: M+H+ 416.
