Reaction Steps

Method as described for intermediate 5 using (S)-4-(4-chloro-6-(5-fluoro-2-(methylsulfonyl)phenyl)pyrimidin-2-yl)-3-methylmorpholine (intermediate 16) and 1-(2,2-difluoroethyl)-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (intermediate 20). Purification was achieved using flash chromatography (20-90% EtOAc in petroleum ether (40:60). The material was further purified by prep HPLC (low pH) to afford a white solid (20 mg, 23%).
