A mixture of ethyl 10-(((dimethylamino)(oxo)acetyl)amino)-3-hydroxy-4-oxo-4,6,7,8,9,10-hexahydro-7,10-ethanopyrimido[1,2-a]azepine-2-carboxylat (30 mg, 0.076 mmol), (4-fluoro-2-(5-methyl-1H-1,2,3-triazol-1-yl)phenyl)methanamine, bis-hydrochloride salt (42.7 mg, 0.153 mmol) and triethylamine (0.1 ml, 0.717 mmol) in ethanol (2 mL) was heated at 90° C. for 18 h. The reaction mixture was then cooled, concentrated and purified on preparative reversed phase HPLC to afford the title compound (10 mg, 21% yield) as an off-white solid. 1H NMR (500 MHz, CDCl3) δ: 1.66-1.77 (m, 2 H) 1.90-2.01 (m, 2 H) 2.14-2.24 (m, 2 H) 2.27 (s, 3 H) 2.39-2.47 (m, 2 H) 2.50 (br. s., 1 H) 2.89 (s, 3 H) 3.19 (s, 3 H) 4.15 (d, J=3.97 Hz, 2 H) 4.23 (d, J=6.41 Hz, 2 H) 6.99 (dd, J=8.24, 2.44 Hz, 1 H) 7.26-7.33 (m, 2 H) 7.62-7.68 (m, 2 H) 8.86 (t, J=6.10 Hz, 1H) 11.73 (br. s., 1 H). LCMS (M+H)=553.22. HPLC purity: >95%.
