実験手順

To a stirred solution of 10-amino-3-(benzyloxy)-2-(5-(4-fluorobenzyl)-1,3-thiazol-2-yl)-7,8,9,10-tetrahydro-7,10-ethanopyrimido[1,2-a]azepin-4(6H)-one, Example 5 (35 mg, 0.085 mmol) in DMF (2 mL) was added 2-(dimethylamino)-2-oxoacetic acid (19.87 mg, 0.170 mmol), N,N-diisoproplylethylamine (0.119 mL, 0.679 mmol), HATU (64.5 mg, 0.170 mmol) and DMAP (5.18 mg, 0.042 mmol) and the resulting mixture stirred at room temperature for 16 h. The mixture was purified by preparative HPLC to afford the title compound (7 mg, 0.013 mmol, 15.32% yield) as a light green solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.17 (1H, br. s.), 9.04 (1H, br. s.), 7.87 (1H, br. s.), 7.36 (2H, dd, J=8.16, 5.65 Hz), 7.19 (2H, t, J=8.78 Hz), 4.29 (2H, s), 4.06 (2H, d, J=3.51 Hz), 3.04 (3H, s), 2.87 (3H, s), 2.33-2.45 (3H, m), 2.03-2.14 (2H, m), 1.79-1.90 (2H, m), 1.60-1.71 (2H, m). LCMS (M+H)=512.01.
