Procedure

A mixture of N-[2-[[[(4-fluoro-3-methylphenyl)methyl]amino]carbonyl]-6,7,8,9-tetrahydro-3-hydroxy-7-[[[(4-methylphenyl)sulfonyl]oxy]methyl]-4-oxo-7,10-ethanopyrimido[1,2-a]azepin-10(4H)-yl]-N,N′,N′-trimethyl-ethanediamide, Intermediate 28, (50 mg, 0.073 mmol) was treated with TBAF, 1M in THF (1.5 mL, 1.500 mmol) and 4 Å molecular sieves. The mixture was then stirred for 30 min at room temp and heated at 80° C. for 18 h. After cooling the reaction mixture was concentrated and purified by preparative HPLC to afford the title compound (14 mg, 0.025 mmol, 34.2% yield) as an off-white solid. 1H NMR (500 MHz, CDCl3) δ: 12.18 (1H, br. s.), 9.60 (1H, br. s.), 7.17-7.26 (2H, m), 6.94 (1H, t, J=8.85 Hz), 4.75 (1H, d, J=14.95 Hz), 4.56-4.65 (1H, m), 4.39-4.50 (1H, m), 4.28 (1H, d, J=2.75 Hz), 4.19 (1H, d, J=2.75 Hz), 3.42-3.57 (2H, m), 3.05 (3H, s), 3.03 (3H, s), 3.01 (3H, s), 2.27 (3H, s), 2.07-2.18 (3H, m), 1.80-1.88 (1H, m), 1.70-1.78 (2H, m), 1.42-1.52 (1H, m). LCMS (M+H)=532.4.
