3-(4-Chlorophenylamino)-2-methylsulfonyl-3-methylsulfanyl-propenenitrile (0.242 g, 0.8 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 0.240 g (85%) of the title compound. Mp 160.5-161.5° C. 1H NMR (200 MHz, CDCl3): δ=0.87 (s, 9H), 0.97 (d, 3H), 3.1 (m, 4H), 7.07 (d, 1H), 7.49 (d, 2H); Analysis: calc. for C16H22ClN3O2S: C, 54.00%; H, 6.23%; N, 11.81%; Found: C, 54.26%; H, 6.33%; N, 11.76%.
