2-(4-Chlorophenylsulfonyl)-3-(3-cyanophenylamino)-3-methylsulfanyl-2-propenenitrile (0.300 g, 0.6 mmol) was stirred in cyclopentylamine (1 ml) for 48 h at 100° C. under nitrogen in a sealed flask. Work up as described in Example 1, 2) gave 51 mg (16%) of the title compound as light brown crystals. 1H NMR (200 MHz, CDCl3): δ=1.43-1.54 (m, 4H), 1.68-1.78 (m, 4H), 3.64 (sextet, 1H), 7.07 (d, 1H), 7.21 (s, 1H), 7.40-7.55 (m, 6H), 7.77 (dd, 2H)
