실험 절차

A solution of intermediate 35, 3-(benzyloxy)-10,10-dimethyl-4-oxo-6,7,8,10-tetrahydro-4H-pyrimido[2,1-c][1,4]oxazepine-2-carboxylic acid in anhydrous dimethylformamide (4 mL) was treated with HATU (0.278 g, 0.70 mmol) and stirred for 10 minutes. The reaction mixture was treated with 2-(aminomethyl)-5-fluoro-N-methylbenzamide trifluoroacetic acid salt (0.24 g, 0.8 mmol), followed by dimethylaminopyridine (0.121 g, 0.97 mmol), then stirred for 4 hours at 60° C. Following this, the solvent was removed in vacuo and the remaining residue dissolved in ethyl acetate (15 mL) and washed with 1.0 N HCl (15 mL). The organic layer was dried (sodium sulfate), filtered, and concentrated to dryness. The crude product was purified by flash column chromatography (SiO2), eluting with ethyl acetate. Fractions containing the product were pooled, concentrated to dryness and triturated with ether to provide 0.366 g of the title compound as a white glassy solid. 1H NMR (500 MHz, d6-acetone) δ ppm: 8.71–8.82 (1H, m), 7.84–7.95 (1H, br), 7.47–7.62 (4H, m), 7.27–7.40 (5H, m), 7.20 (1H, dt, J=8.5, 2.7 Hz), 5.15–5.21 (2H, br s), 4.48–4.60 (4H, m), 2.96 (2H, s), 2.94 (2H, s), 1.62–1.64 (6H, s).
