Procedure

In a 100 mL round bottom flask to a solution of 2-chloro-5-fluoro-N-(2,2,6,6,-tetramethylpiperidin-4-yl)pyrimidin-4-amine (Compound 15; 0.18 g, 0.63 mmol) in 10 mL iPrOH, 4-cyclopropyl-3-(1H-tetrazol-1-yl)benzeneamine (0.18 g, 0.88 mmol) and TosOH (0.095 g, 0.50 mmol) were added. The reaction mixture was heated at 100° C. for 3 hours. LCMS analysis indicated the complete consumption of the mono-SNAr product and appearance of Compound III-118. The reaction mixture was then cooled to room temperature and volatiles were removed under reduced pressure. The crude reaction mixture was purified by column chromatography using DCM/2 M NH3 in MeOH to get tan solid that was further purified by tituration using DCM/hexanes.
