Treatment of 9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)-2-amino-6-chloropurine (1) with TMS-Cl and benzyltriethylammonium nitrite (BTEA-NO2) in dichloromethane gave the crystalline 2,6-dichloropurine nucleoside 2, and acetyl chloride/BTEA-NO2 was equally effective (～85%, without chromatography). TMS-Br/tert-butyl nitrite/dibromomethane gave crystalline 2-bromo-6-chloro analogue 3 (85%). (Chloro or bromo)-dediazoniation of 3′,5′-di-O-acetyl-2′-deoxyadenosine (4) gave the 6-[chloro (5, 63%) or bromo (6, 80%)]purine deoxynucleosides, and 2′,3′,5′-tri-O-acetyladenosine (8) was converted into the 6-chloropurine nucleoside 9 (71%).
