Reaction Steps

3-(3-Methoxy-5-trifluoromethyl-phenylamino)-2-methylsulfonyl-3-methylsulfanyl-propenenitrile (0.22 g, 0.6 mmol) was stirred in 1,2,2-trimethylpropylamine (1 ml) for 17 h at 75° C. under nitrogen. Work-up as described in EXAMPLE 17, 2) without chromatography gave 100 mg (40%) of the title compound. Mp 110-113° C. 1H NMR (200 MHz, CDCl3): δ=0.87 (s, 9H), 1.01 (d, 3H), 3.08 (m, 1H), 3.10 (s, 3H), 3.87 (s, 3H), 6.81 (br s, 1H), 6.95 (br s, 1H), 6.97 (br s, 1H); Analysis: calc. for C18H24N3O3S: C, 51.54%; H, 5.77%; N, 10.02%; Found: C, 51.77%; H, 6.05%; N, 9.80%.
