A mixture of 3-(benzo[1,3]dioxol-5-ylamino)-2-methanesulfonyl-3-methylsulfanyl-2-propenenitrile(0.800 g, 2.5 mmol) and 1,1-dimethylpropylamine (2.92 ml) in 10 ml of acetonitrile was stirred and refluxed for one week under nitrogen. The reaction mixture was concentrated and the residue dissolved in dichloromethane, washed twice with 1N aqueous HCl, once with brine, and trice with water. The organic phase was dried (sodium sulphate) and evaporated to afford the title compound as white crystals. Mp 86-88° C. 1H NMR (200 MHz, DMSO-d6): δ=0.90 (t, 3H), 1.34 (s, 6H), 1.70 (q, 2H), 3.04 (s, 3H), 6.66 (dd, 1H), 6.74 (d, 1H), 6.88 (d, 1H), 7.21 (s, 1H), 8.19 (s, 1H).
