실험 절차

A suspension of tert-butyl methyl(2-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-(trifluoromethyl)pyridin-2-yloxy)ethyl)carbamate (440 mg), 3-amino-6-chloro-4-(methylamino)picolinonitrile (135 mg), tris(dibenzylideneacetone)dipalladium (0) (34.9 mg), tricyclohexylphosphine (25.7 mg) and potassium phosphate (327 mg) in 1,4-dioxane (10 ml) and water (5 ml) was stirred at 100° C. for 2 h. The reaction mixture was cooled and partitioned between water and ethyl acetate, washed with water, brine, dried over sodium sulfate, filtered and concentrated. Purified by Biotage SNAP cartridge KP-Sil column (25 g, heptane:ethyl acetate=1:0, 3:1, 2:1, 1:1 to 1:2) to give 170 mg orange amorphous as tert-butyl 2-(5-amino-6-cyano-4-(methylamino)-5′-(trifluoromethyl)-2,3′-bipyridin-6′-yloxy)ethyl(methyl)carbamate (49%).
