Procedure

To a solution of intermediate 195, (R)-N-(2-(2-(azidomethyl)-5-oxopyrrolidin-1-yl)-4-fluorobenzyl)-3-(benzyloxy)-9,9-dimethyl-4-oxo-4,6,7,9-tetrahydropyrimido[2,1-c][1,4]oxazine-2-carboxamide, (0 030 g, 0.052 mmol) in CH2Cl2 (1 mL) was added CF3CO2H (1 mL) at 23° C. The reaction mixture was stirred at 23° C. for 3 h. Toluene (20 mL) was then added and the solvents evaporated in vacuo. The residue was purified by preparative HPLC (YMC-Pack C-18) to afford the title compound (0.008 g, 31%): 1H NMR (400 MHz, MeOD) δ ppm: 7.55 (1H, dd, J=6.6 Hz), 7.16 (2H, m), 4.47–4.24 (2H, m), 4.05 (2H, m), 3.98 (2H, m), 3.56 (2H, s), 2.70–2.45 (4H, m), 2.11 (1H, m), 1.64 (3H, s), 1.61 (3H, s). HRMS calcd for C22H25N7O5F: 486.1901. Found 486.1923.
