Reaction Steps

3-(Benzo[1,3]dioxol-5-ylamino-2-(4-chlorophenylsulfonyl)-3-methylsulfanyl-2-propenenitrile (0.327 g, 0.8 mmol) was stirred in 1,2,2-trimethylpropylamine (1 ml) for 22 h at 100° C. under nitrogen in a sealed flask. Work up as described in Example 1, 2) gave 182 mg (49%) of the title compound. Mp 160.5-162° C. 1H NMR (200 MHz, CDCl3): δ=0.78 (s, 9H), 0.9 (d, 3H), 3.22 (m, 1H), 6.0 (br s, 2H), 6.48 (m, 2H), 6.78 (br d, 1H), 7.48 (d,2H), 7.83 (d, 2H).
