The title compound was prepared as described for Example 12 from 2-tert-butyl-4-[(3-chloropropyl)amino]-5-phenylisothiazol-3(2H)-one 1,1-dioxide and thiophenol at 100° C. for 45 mins. The reaction mixture was filtered, evaporated to dryness and the residue was purified by silica gel column chromatography (Horizons Biotage) using 10-20% EtOAc in hexane as eluent to give the title compound (0.076 g, 65%). 1H NMR (500 MHz CDCl3): δ 7.52-7.48 (m, 2H), 7.46-7.38 (m, 3H), 7.32-7.18 (m, 5H), 5.32 (t, 1H), 3.02-2.96 (m, 2H), 2.70 (t, 2H), 1.74 (s, 9H), 1.68-1.60 (m, 2H); 13C NMR (125 MHz CDCl3): δ 159.8, 135.6, 135.1, 131.8, 129.4, 129.9, 129.3, 128.9, 126.7, 125.1, 107.5, 61.8, 42.8, 31.0, 28.9, 27.9; Mass Spectrum: M+H+ 431.
