Reaction Steps

The title compound was prepared as described for Example 24 from 1 equivalent of [(5-methylisoxazol-3-yl)methyl]-amine, 2-tert-butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide and 1 equivalent TEA with a reaction time of 45 mins. The mixture was evaporated and purified by silica gel column chromatography (Horizons Biotage) using 35% EtOAc in pentane as eluent to give the title compound (0.070 g, 56%). 1H NMR (500 MHz CDCl3): δ 7.52-7.48 (m, 2H), 7.46-7.41 (m, 3H), 5.73 (s, 1H), 5.66 (t, 1H), 5.07 (d, 2H), 2.39 (s, 3H), 1.74 (s, 9H); 13C NMR (125 MHz CDCl3): δ 170.7, 159.9, 159.4, 134.8, 131.6, 130.1, 128.9, 124.7, 109.3, 100.4, 61.9, 40.4, 27.8, 12.5; Mass Spectrum: M+H+ 376
