Reaction Steps
2-tert-Butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide (0.175 g, 0.58 mmol), ethylamine hydrochloride (0.056 g, 0.69 mmol) and TEA (0.23 g, 2.31 mmol) was dissolved in dry DMF (3 ml) and heated in a microwave reactor at 130° C. for 30 mins. The reaction mixture was purified by preparative HPLC to yield the title compound (0.099 g, 55%). 1H NMR (500 MHz, CDCl3): δ 7.51-7.46 (m, 2H), 7.43-7.38 (m, 3H), 5.21-5.12 (m, 1H), 2.89-2.80 (m, 2H), 1.72 (s, 9H), 1.01 (t, 3H); 13C NMR (125 MHz, CDCl3): δ 159.9, 135.2, 131.7, 129.7, 128.7, 125.4, 107.1, 61.7, 39.3, 27.8, 15.0; Mass Spectrum: M−H+ 309.
