実験手順
In the manner of Example 36, part (b), (E)-4-[1,3-bis(cyclohexylmethyl)-1,2,3,6-tetrahydro-2,6-dioxo-9H-purin-8-yl]cinnamic acid was converted to (E)-1,3-bis(cyclohexylmethyl)-8-(3-(2-(1H-imidazol-1-ylcarbonyl)vinyl)phenyl)-9H-purin-2,6(1H,3H)-dione as a yellow powder. Such a sample (2.50 g, 4.62 mmol) was stirred at reflux in acetonitrile (75 ml) with potassium carbonate (1.28 g, 9.25 mmol) and methanol, (10 ml) for 24 hours. The mixture was cooled to room temperature and filtered and the filtrate-wash was adjusted to pH ˜3 by addition of 6N hydrochloric acid. The resulting precipitate was filtered and washed with methanol and dried to give (E)-4-[1,3-bis(cyclohexylmethyl)-1,2,3,6-tetrahydro-2,6-dioxo-9H-purin-8-yl]cinnamic acid methyl ester (1.70 g, 74%) as a white solid. 1H-NMR (300 MHz, DMSO-d6) δ: 8.16 (d, J=8.2 Hz, 2H, phenylCH), 7.83 (d, J=8.4 Hz, 2H, 2 phenylCH), 7.63 (d, J=15.9 Hz, 1H, CH═), 6.70 (d, J=15.9 Hz, 1H, CH—), 3.95 (d, J=7.0 Hz, 2H, CH2N), 3.75 (d, J=6.8 Hz, 2H, CH2N), 3.70 (s, 3H, CH3), 2.0-1.50 and 1.20-0.80 (m, 22H, 2C6H11).
