Procedure

A mixture of 10 mmol (2387 mg) 6-chloro-9-(tetrahydropyran-2-yl)purine (prepared from 10 mmol (1546 mg) of 6-chloropurine), 12 mmol (1478 mg) 3-hydroxybenzylamine, and 5 mL of triethylamine was refluxed in n-butanol for 3 hours. After removal of the n-butanol by vacuum evaporation water was added to remove the n-butanol residues. The resulting material was treated with water and partitioned into ethyl acetate. The ethyl acetate phase was evaporated and the residuum subsequently washed with 30 ml of diethylether. The solid residue was filtered off and the crude product crystallized from methanol. Yield 90%, white solid. TLC (EtOAc:hexane (1:1) (v:v): single spot; HPLC: purity>99%. 1H-NMR (400 MHZ, DMSO): 1.57m (2H); 1.70m (1H); 1.95m (2H); 2.27qq (1H, Ja=11.7 Hz, Jb=4.0 Hz); 3.66m (1H); 4.0d (1H); 4.63bs (2H); 5.67dd (1H, Ja=11.3 Hz, Jb=1.8 Hz); 6.58dd (1H, Ja=8.2 Hz, Jb=1.5 Hz); 6.73 (d, 1H, J=7.7 Hz); 7.07t (1H, J=7.7 Hz); 8.21s (1H); 8.33bs (1H); 8.36bs (1H); 9.26s (1H). MS (ES): [M+H]+=326 (100).
