Versuchsvorschrift

The mixture of 3-[4-bromo-5-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-3-yl)-1,3-thiazol-2-yl]-2-methylpyrazolo[1,5-a]pyridine (0.0700 g, 0.142 mmol), p-Chloro-N-methylaniline (33.5 mg, 0.236 mmol), Tris(dibenzylideneacetone)dipalladium(0) (4.4 mg, 0.0048 mmol.), racemic 1,1′-binaphthalene-2,2′-diylbis(diphenylphosphine) (8.8 mg, 0.014 mmol) and Sodium tert-butoxide (22.7 mg, 0.236 mmol) in dry Toluene (2.0 mL, 19 mmol) was degassed by vacuum and backfilling with N2 for 5 times, sonicated under N2 for 1 min to dissolve all material, degassed for 5 more times. The resulted brown solution was heated under N2 in a capped vial to 112° C. for 18 hours. The mixture was partitioned in EtOAc (80 mL) and water (30 mL). The EtOAc layer was washed with water, brine, dried over Na2SO4, filtered, rotavaped to give a crude product. Chromatograph in a 24 g ISCO column using EtOAc/hexane (0/100 to 40/60) afforded a solid product (0.059 g, 75% yield).
