Reaction Steps

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), 4-(bromomethyl)benzonitrile (0.054 g, 0.275 mmol), 1-benzyl-1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine on polystyrene (0.055 g, 0.413 mmol) in DMF (2 ml) was heated in a microwave reactor at 150° C. for 7 mins. The reaction mixture was filtered, evaporated to dryness and the residue was purified by preparative HPLC to give the title compound (0.040 g, 30%); 1H NMR (500 MHz CDCl3): δ 7.59 (d, 2H), 7.52-7.49 (m, 2H), 7.48-7.42 (m, 3H), 7.37 (d, 2H), 5.21 (d, 1H), 3.41 (s, 2H), 3.01-2.90 (m, 1H), 2.65-2.56 (m, 2H), 1.74 (s, 9H), 1.69-1.60 (m, 4H), 1.44-1.34 (m, 2H); 13C NMR (125 MHz CDCl3): δ 159.9, 144.5, 134.2, 132.3, 131.9, 129.9, 129.4, 128.9, 125.4, 119.1, 111.1, 106.9, 62.3, 61.8, 51.9, 50.1, 32.5, 27.8; Mass Spectrum M+H+ 479.
