4-Chloro-2-isopropyl-5-phenylisothiazol-3(2H)-one 1,1-dioxide (0.200 g, 0.70 mmol), 1-(4-trifluoromethyl-pyrimidin-2-yl)-piperidin-4-ylamine (0.190 g, 0.77 mmol) and TEA (0.078 g, 0.77 mmol) was dissolved in dry MeCN (3 ml) and heated in a microwave reactor at 120° C. for 30 mins. The reaction mixture was purified by silica gel column chromatography using a 65:35 mixture of heptane and EtOAc as eluant, to give the title compound (0.280 g, 81%). 1H NMR (500 MHz, CDCl3): δ 8.45-8.41 (m, 1H), 7.58-7.52 (m, 2H), 7.49-7.42 (m, 3H), 6.74-6.70 (m, 1H), 5.26-5.19 (m, 1H), 4.59-4.51 (m, 2H), 4.41 (hep, 1H), 3.26-3.16 (m, 1H), 2.58-2.49 (m, 2H), 1.78-1.71 (m, 2H), 1.57 (d, 6H), 1.35-1.24 (m, 2H); 13C NMR (125 MHz, CDCl3): δ 161.2, 160.3, 158.7, 156.6, 156.3, 134.5, 131.9, 130.2, 129.0, 125.3, 121.8, 119.6, 107.2, 104.9, 50.7, 47.9, 42.4, 32.2, 20.4; Mass Spectrum: M−H+ 496.
