Reaktionsschritte

A solution of tert-butyl 6-(3-aminopyridin-4-yl)-2-(trifluoro-methyl)pyrimidin-4-ylcarbamate (1.0 equiv.), 3-amino-6-bromopicolinic acid (1.0 equiv.), HOAt (1.0 equiv.), and EDC (1.0 equiv.) in DMF at a concentration of (0.2 M) was stirred for 3 hrs then heated to 50° C. overnight (homogeneous solution). Water was added to the reaction and the precipitate was filtered. The solid was further purified via SiO2 column chromatography eluting with DCM/MeOH (10%) to yield a brown solid as the desired product (81%). LCMS (m/z): 554.1/556.1 (MH+); LC Rt=3.77 min.
