Reaction Steps

To stirred solution of 3-(benzyloxy)-9,9-dimethyl-4-oxo-4,6,7,9-tetrahydropyrimido[2,1-c][1,4]oxazine-2-carbohydrazide (0.170 g, 0.49 mmol) and Et3N (0.14 mL, 1 mmol) in CH2Cl2 (10 mL) was added 2-(4-fluorophenyl)acetyl chloride (69 mL, 0.5 mmol) and the mixture stirred 2 h at room temperature. The reaction mixture was purified by preparative HPLC on a C18 column using water/MeOH containing 0.1% TFA as eluent to afford the title compound (0.078 g, 33% yield) as a white solid. 1HNMR (500 MHz, CDCl3) δ: 9.97 (1H, d, J=7.0 Hz), 8.42 (1H, d, J=6.7 Hz), 7.54 (2H, d, J=6.7 Hz), 7.35-7.27 (5H, m), 7.05 (2H, t, J=8.6 Hz), 5.36 (2H, s), 4.04-3.98 (4H, m), 3.64 (2H, s), 1.60 (6H, s). HRMS (M+H) calcd for C25H26N4O5F: 481.1887. found: 481.1866.
