Reaction Steps

4-Chloro-2-isopropyl-5-phenylisothiazol-3(2H)-one 1,1-dioxide (150 mg, 0.525 mmol) was dissolved in dry DMF (1 mL) under nitrogen atmosphere. 1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]azetidin-3-amine (133 mg, 0.530 mmol) was added followed by TEA (53 mg, 0.525 mmol) and the reaction mixture was heated in a microwave reactor for at 120° C. for 20 mins. The mixture was diluted with EtOAc, washed with saturate aqueous NaHCO3, dried with Na2SO4, filtered and evaporated. The crude product was purified on a Biotage Horizon HPFC system using Heptane and EtOAc as eluant affording the title compound (223 g, 84.0%). 1H NMR (500 MHz, CDCl3): δ 1.60 (d, 6H), 4.01-4.06 (m, 3H), 4.10-4.15 (m, 2H), 4.40-4.48 (m, 1H), 5.62 (bs, 1H), 7.51 (s, 5H), 7.59 (s, 1H), 8.25 (s, 1H); 13C NMR (125 MHz, CDCl3): δ 20.38, 44.61, 48.06, 59.87, 109.52, 115.56, 117.98 (q, JC-F=33.6 Hz), 124.42, 124.75, 129.29, 130.48, 131.49, 134.49, 135.16, 143.70, 156.92, 158.26; Mass Spectrum: M+H+ 501.1.
