Procedure

A 25 mL round bottom flask charged with 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, (900 mg, 1.316 mmol), potassium acetate (388 mg, 3.95 mmol), K2CO3 (182 mg, 1.316 mmol), EtOH (1 ml, 17.13 mmol), N,N-dimethylacetamide (6 mL) and stirred in a pre-heated oil bath (145° C.) for 3 h. After cooling the reaction was quenched with 1 N HCl (3 mL), diluted with EtOAc (100 mL) and washed with water (3×25 mL). The combined aqueous layers were extracted with EtOAc (2×50 mL). The combined organic layers were washed with brine (50 mL), dried (Na2SO4), filtered and concentrated to afford a brown solid which was crystallized from ethanol (˜30 mL) to give the title compound (250 mg, 0.448 mmol, 34.1% yield) as white crystals. 1H NMR (500 MHz, CDCl3) δ: 9.59 (1H, t, J=5.95 Hz), 7.24 (1H, d, J=7.63 Hz), 7.16-7.22 (1H, m), 6.94 (1H, t, J=9.00 Hz), 4.76 (1H, d, J=15.26 Hz), 4.58-4.65 (1H, m), 4.42-4.49 (1H, m), 3.48-3.57 (3H, m), 3.37-3.47 (1H, m), 3.05 (3H, s), 3.04 (3H, s), 3.01 (3H, s), 2.26 (3H, d, J=1.53 Hz), 2.08-2.16 (3H, m), 1.77-1.85 (1H, m), 1.67-1.74 (2H, m), 1.41-1.51 (1H, m).
