3-(3,5-Bis(trifluoromethyl)phenylamino)-2-(4-chloro-phenylsulfonyl)-3-methylsulfanyl-2-propenenitrile (0.400 g, 0.8 mmol) was stirred in isopropylamine (2 ml) at 80° C. in a sealed flask for 20 h. Work up as described in Example 1, 2) gave 254 mg (62%) of the title compound as white crystals. Mp 197-198.5° C. 1H NMR (300 MHz, CDCl3): δ=1.5 (d, 6H), 3.37 (m, 1H), 7.42 (s, 2H), 7.48 (d, 2H), 7.67 (s, 1H), 7.79 (d, 2H); MA calc for C20H16ClF6N3O2S: C, 46.93%; H, 3.15%; N, 8.21%. Found: C, 47.16%; H, 3.14%; N, 8.10%.
