Reaction Steps

To Intermediate 4-Amino-3-[9-(2,2,2-trifluoro-acetyl)-2,9-diaza-spiro[5.5]undec-2-yl]-benzonitrile was added 2-thiophen-2-yl-thiazole-4-carboxylic acid (098 eq) in DMF (1 mL). Then, a solution of N,N-diisopropylethylamine (1.5 eq) HATU (1.5 eq) was added. The resulting reaction was stirred at room temperature for 15 hours and then concentrated and treated with 3 mL of (4:1) TFA:H2SO4. The reaction mixture was concentrated and purified using reverse phase HPLC to provide 2-Thiophen-2-yl-thiazole-4-carboxylic acid {4-carbamoyl-2-[9-(2,2,2-trifluoro-acetyl)-2,9-diaza-spiro[5.5]undec-2-yl]-phenyl}-amide. HPLC-MS RT=4.46 min, mass calculated for formula C26H26F3N5O3S2 577.14, observed LCMS m/z 578.21 (M+H).
