Reaction Steps

The above 2',3',5'-tri-O-benzoyl-2-chloro-N-(1-piperidinyl)adenosine (19.2 g, 27.5 mmol) was dissolved in methanolic ammonia (150 ml) (previously saturated at -10° C.) and stirred at room temperature for 18 hours. The precipitated benzamide was removed by filtration, and the filtrate was evaporated to a fawn oil, which was triturated with diethyl ether to provide the title compound (6.0 g, 57%) as a white foam, 1H NMR (400 MHz, Me2SO-d6) δ 3.55 (1H, m, H-5'a), 3.66 (1H, m, H-5'b), 3.94 (1H, q, H-4'), 4.12 (1H, m, H-3'), 4.50 (1H, q, H-2'), 5.82 (1H, d, H-1'), 8.40 (1H, s, H-8); HPLC retention time 26.57 (gradient elution, 5-25% acetonitrile/0.1M pH 3.3 ammonium sulphate buffer: 214 nm detector); purity 99%.
