実験手順

To a stirring solution of 2-[5-(3,4-diamino-5-tetrahydrofuran-2-yl-phenyl)pyrimidin-2-yl]propan-2-ol (9) (32.10 g, 102.1 mmol) in 1,4-dioxane (160.5 mL, Sigma-Aldrich 360481) was added pH 3.5 buffer (240.8 mL), prepared by dissolving NaOAc trihydrate (34.5 g) in 1N aqueous H2SO4 (240 mL). 1-Ethyl-3-(N-(ethylcarbamoyl)-C-methylsulfanyl-carbonimidoyl)urea (10) (28.46 g, 122.5 mmol, CB Research and Development) was added to the reaction mixture and stirred at reflux overnight (HPLC showed 99% consumption of starting diamine). The reaction mixture was cooled to room temperature and poured portion-wise (frothing) into a stirring solution of aqueous saturated NaHCO3 (480 mL) and water (120 mL) giving pH 8-9. This was stirred for 30 minutes, the solid was collected by filtration, washed copiously with water to neutral pH, and then more sparingly with EtOH. The solid was dried under reduced pressure giving (11) as an off-white solid (34.48 g, 82% yield; 99.4% HPLC purity). LCMS (C18 column eluting with 10-90% CH3CN/water gradient over 5 minutes with formic acid modifier) M+1: 411.41 (1.73 min). 1H NMR (300 MHz, MeOD) δ 9.02 (s, 2H), 7.62 (s, 1H), 7.37 (s, 1H), 5.31 (s, 1H), 4.23 (dd, J=14.5, 7.3 Hz, 1H), 4.01 (dd, J=15.0, 7.1 Hz, 1H), 3.38-3.28 (m, 2H), 2.58-2.46 (m, 1H), 2.16-2.05 (m, 2H), 2.02-1.88 (m, 1H), 1.63 (s, 6H), 1.22 (t, J=7.2 Hz, 3H) ppm.
