Procedure

To a solution of 3-(3,5-bis(trifluoromethyl)phenylamino)-2-(4-chloro-phenylsulfonyl)-3-methylsulfanyl-2-propenenitrile (0.300 9, 0.6 mmol) in dry acetonitrile (1.0 ml), triethylamine (0.100 ml, 0.7 mmol) and 5-amino-3-cyclopropyl-1-methyl pyrazole (0.100 g, 0.7 mmol) were added. The reaction mixture was stirred for 41 h at 80° C. under nitrogen and then concentrated. The residue was worked up as described in Example 17,2) to give 90 mg (25%) of the title compound. 1H NMR (200 MHz, CDCl3): δ=0.7 (m, 2H), 0.9 (m, 2H), 1.85 (m, 1H), 3.5 (s, 3H), 5.3 (s, 1H), 5.4 (s, 1H), 5.85 (s, 1H), 7.28 (s, 2H), 7.53 (d, 2H), 7.63 (s, 1H), 7.8 (d, 2H); EI SP/MS: 589 (M+).
