3-(3,5-Bis(trifluoromethyl)phenylamino)-2-methanesulfonyl-3-methylsulfanyl-2-propenenitrile (0.323 g, 0.8 mmol) was stirred in isopropylamine (1 ml) for 17 h at 75° C. under nitrogen. Work-up as described in Example 17, 2) without chromatography gave 247 mg (74%) of the title compound. Mp 188.5-191° C. 1H NMR (200 MHz, CDCl3): δ=1.15 (d, 6H), 3.15 (s, 3H), 3.40 (m, 1H), 7.56 (s, 2H), 7.68 (s, 1H). Analysis: calc. for C15H15F6N3O2S: C, 43.38%; H, 3.64%; N, 10.12%. Found: C, 43.52%; H, 3.63%; N, 9.98%.
