Reaction Steps
A mixture of 4-(7-(6-cyano-5-(trifluoromethyl)pyridin-3-yl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]octan-5-yl)-2-fluorobenzoic acid (Compound 224, 68 mg, 0.14 mmol), benzylamine (22 mg, 0.21 mmol), HATU (70 mg, 0.18 mmol), and DIEA (40 μL, 0.21 mmol) in DMF (3 mL) was stirred at room temperature for 3 h. The crude reaction mixture was purified by reverse phase HPLC (acetonitrile/water:TFA) to afford 51 mg of N-benzyl-4-(7-(6-cyano-5-(trifluoromethyl)pyridin-3-yl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]octan-5-yl)-2-fluorobenzamide as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.22 (d, 1H), 9.12 (t, 1H), 8.75 (d, 1H), 7.87 (t, 1H), 7.49 (dd, 1H), 7.40 (dd, 1H), 7.37-7.31 (m, 4H), 7.29-7.24 (m, 1H), 4.51 (d, 1H), 2.69-2.63 (m, 2H), 2.55-2.44 (m, 2H), 2.03-1.94 (m, 1H), 1.62-1.56 (m, 1H). LCMS [M+1]+ 554.5.
