실험 절차

A 10 mL microwave reaction tube was charged with compound 245 (80.0 mg, 295 μmol), 5-(4-(2-(t-butyldimethylsilyloxy)ethyl)piperidin-1-yl)-2-chloropyridine (293) (105 mg, 295 μmol), tris(dibenzylideneacetone)dipalladium (0) (20.3 mg, 22.1 μmol), 4,5-bis(diphenylphosphino)-9,9-dimethyl-9H-xanthene (25.6 mg, 44.2 μmol), sodium t-butoxide (56.7 mg, 590 μmol), and dioxane (3 mL). The reaction was purged with argon and heated with microwave energy (300 W) for 3.5 hours at 120° C. The reaction was taken up in ethyl acetate (40 mL) and washed with water (30 mL) and brine (30 mL). The organic phase was dried (MgSO4) and evaporated to give an orange oil. Silica gel chromatography (gradient elution hexanes+2.5% TEA/0-100% ethyl acetate+2.5% TEA) afforded compound 294 as a yellow solid (113 mg, 65%).
