Versuchsvorschrift

A suspension of 5-methyl-1-[4-(trifluoromethyl)phenyl]-1H-pyrazole-4-carboxamide (538 mg), 5-bromo-2-(1,4-dioxaspiro[4.5]decan-7-en-8-yl)-3-methylpyridine (620 mg) described in Reference Example 105, tris(dibenzylideneacetone)dipalladium (0) (18 mg), 2-di-tert-butylphosphino-3,4,5,6-tetramethyl-2′,4′,6′-triisopropylbiphenyl (48 mg), trisodium phosphate (509 mg) and tert-butanol (10 ml) was stirred at 110° C. After the reaction, the reaction solution was left stand, water was added and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate and concentrated. The resulting residue was purified with a silica gel column chromatography (chloroform/methanol) to give N-[6-(1,4-dioxaspiro[4.5]decan-7-en-8-yl)-5-methylpyridin-3-yl]-5-methyl-1-[4-(trifluoromethyl)-phenyl]-1H-pyrazole-4-carboxamide (856 mg) as a pale yellow solid.
