Procedure
Prepared in analogy to example 160b, starting from 8-bromo-6-methyl-[1,2,4]triazolo[1,5-a]pyridin-2-amine and 3-((tert-butoxycarbonylamino)methyl)phenylboronic acid. The title compound was obtained as an off-white solid (yield: 99%) after precipitation from diethyl ether. MS ISP (m/e): 354.4 (80) [(M+H)+], 298.4 (100), 237.2 (99).
