Procedure

A mixture of 2-tert-butyl-5-phenyl-4-(piperidin-4-ylamino)isothiazol-3(2H)-one 1,1-dioxide (Example 75) (0.100 g, 0.275 mmol), 2-(trifluoromethyl)benzoyl chloride (0.049 ml, 0.330 mmol) and 2-tert-butylimino-2-diethylamino-1,3-dimethyl-perhydro-1,3,2-diazaphosphorine on polystyrene (0.600 g, 1.376 mmol) in DCM (2 ml) was stirred at rt for 17 h. The mixture was filtered, evaporated to dryness and the residue was purified by preparative HPLC to give the title compound (0.053 g, 36%). 1H NMR (500 MHz CDCl3): δ 7.68 (t, 1H), 7.61-7.42 (m, 6 h), 7.26 (d, 1H), 7.18 (d, 1H), 5.21 (d, 1H), 4.61-4.46 (m, 1 h), 3.24-3.10 (m, 2H), 2.54-2.38 (m, 2H), 1.88-1.78 (m, 1H), 1.76-1.48 (10H), 1.44-1.32 (m, 1H), 1.26-1.10 (m, 1H); 13C NMR (125 MHz CDCl3): δ 167.4, 167.3, 159.8, 159.7, 134.8, 133.9, 133.8, 132.5, 132.3, 131.9, 131.7, 130.4, 130.2, 129.5, 129.0, 128.9, 127.3, 127.0, 126.9, 125.3, 125.1, 107.8, 107.5, 61.9, 50.3, 50.1, 45.7, 45.5, 41.2, 40.3, 40.1, 32.5, 32.1, 31.9, 31.8, 27.8; Mass Spectrum: M−H+ 534
