Reaction Steps

To a 1,4-dioxane solution (1.0 ml) of the N-[5-chloro-4-[(4-chlorophenylsulfonyl)-(2,5-difluorophenyl)methyl]pyridin-2-yl]propane-1,3-diamine dihydrochloride (76 mg, 0.136 mmol) obtained in Example 173 were added triethylamine (76 μl, 0.54 mmol) and 2-chloropyrimidine (23 mg, 0.20 mmol). The resulting mixture was stirred at 80° C. for 19 hours. The reaction mixture was allowed to cool to room temperature, followed by dilution with ethyl acetate. The diluted mixture was washed with water and brine, dried and concentrated. The residue thus obtained was purified by silica gel chromatography (hexane:ethyl acetate=1:2) to give the title compound (50 mg, 65%). The compound was crystallized in ethanol to afford a white solid (36 mg).
