To a mixture of the 5-(4-(aminomethyl)-2-fluorophenyl)-1-methylpyridin-2(1H)-one 21-7 (obtained in Step 4), 4-(pyrazin-2-yl)benzoic acid 18-3 (5.0 mg, 0.025 mmol), and HATU (9.5 mg, 0.025 mmol) were added N,N-diisopropylethylamine (DIEA, 17 μL, 0.1 mmol) and DMF (0.5 mL). The solution was stirred overnight at room temperature and was subjected directly to reverse phase preparative HPLC to give N-(3-fluoro-4-(1-methyl-6-oxo-1,6-dihydropyridin-3-yl)benzyl)-4-(pyrazin-2-yl)benzamide 21 (2.5 mg). MS m/z 415.2 (M+1).
