実験手順

To a solution of 3-methyl-4-(thietan-3-ylcarbamoyl)-N-trimethylsilanylmethyl-thiobenzimidic acid methyl ester (Example I19) (16 mg) and 1,3-dichloro-5-(1-trifluoromethyl-vinyl)-benzene (see WO 2007/125984) (12 mg) in THF (2 ml) was added at −5° C. tetrabutylammonium fluoride trihydrate (TBAF) (0.41 g) dissolved in THF (1.5 ml). The reaction mixture was stirred at ambient temperature for 16 hours. Water was added and the mixture was extracted twice with ethyl acetate. The combined organic phases were washed with brine, dried over sodium sulfate and concentrated. The residue was purified by chromatography on silica gel (eluent: ethyl acetate/heptanes 1:2) to give 4-[4-(3,5-dichloro-phenyl)-4-trifluoromethyl-4,5-dihydro-3H-pyrrol-2-yl]-2-methyl-N-thietan-3-yl-benzamide (20 mg). 1H-NMR (400 MHz, CDCl3): 7.75-7.25 (m, 6H), 6.30 (s, 1H), 5.45 (m, 1H), 4.90 (d, 1H), 4.45 (d, 1H), 3.82 (d, 1H), 3.55-3.38 (m, 5H), 2.48 (s, 3H) ppm.
