A solution of 2-butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide (0.110 g, 0.33 mmol) and hexylamine (0.100 g, 0.984 mmol) in DMF (0.5 mL) was heated in a microwave reactor at 140° C. for 25 mins. The residue was purified by preparative HPLC (Ace C8 column, 0.1M NH4OAc/MeCN, gradient) to give the title compound (0.060 g, 47%); 1H-NMR (400 MHz, CD3CN): δ 7.49-7.53 (m, 5H), 5.85 (bs, 1H), 3.66 8 (t, 2H), 2.85 (dd, 2H), 1.71-1.80 (m, 2H), 1.37-1.48 (m, 2H), 1.13-1.34 (m, 4H), 0.94-1.09 (m, 7H), 0.82 (t, 3H); Mass Spectrum: M+H 365.
