실험 절차

Prepared in analogy to example 160b, starting from 8-bromo-6-methyl-[1,2,4]triazolo[1,5-a]pyridin-2-ylamine and 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane. The title compound was obtained a light brown solid (yield: 55%) after column chromatography on silica gel using ethyl acetate as eluent.
