2-(4-Chlorophenylsulfonyl)-3-(3,5-dimethoxyphenylamino)-3-methylsulfanyl-2-propenenitrile (0.34 g, 0.8 mmol) was stirred in 1,2,2-trimethylpropylamine (1 ml) for 22 h at 75° C. under nitrogen. Work up as described in EXAMPLE 1, 2) gave 264 mg (72%) of the title compound. Mp 177.5-179° C. 1H NMR (200 MHz, CDCl3): δ=0.82 (s, 9H), 0.95 (d, 3H), 3.2 (m, 1H), 6.13 (d, 2H), 6.32 (t, 1H), 7.45 (d, 2H), 7.82 (d, 2H); EI SP/MS: 478 (M+).
