実験手順

A solution of ethyl 1-[7-(2-chloro-6-fluorobenzyl)-1,3-dimethyl-2,6-dioxo-2,3,6,7-tetrahydro-1H-purin-8-yl]piperidine-3-carboxylate (5.0 g, 10.5 mmol) in 75 mL THF and 25 mL H2O at room temperature was treated with solid LiOH (1.8 g, 43.9 mmol). After stirring overnight the THF was removed under reduced pressure, and the residue was diluted with H2O. The aqueous layer was acidified to pH 4, and the aqueous layer was extracted with CH2Cl2. The combined extracts were concentrated under reduced pressure to give 4.9 g (>99% yield) of the title compound: 1H NMR (CDCl3, 400 MHz) δ7.18 (dt, 2H, J=8.1, 5.7), 7.14 (t, 1H, J=7.6), 6.98-6.90 (m, 1H), 5.57 (AB quartet, 2H, J=15.7, 5.7), 3.51 (s, 3H), 3.42 (dd, 1H, J=12.6, 4.0), 3.30 (s, 3H), 3.20-3.05 (m, 2 H), 2.94-2.83 (m, 1H), 2.59-2.47 (m, 1H), 2.03-1.93 (m, 1H), 1.75-1.40 (m, 3H); LRMS (ESI) m/z 450 (M+H+); TLC (hexanes:EtOAc/1:1) Rf=0.10.
