Procedure
1 mmol of 6-(3-methoxybenzylamino)-2-chloro-9-isopropylpurine was brominated with 1.1 mmol of bromine as described in Example 1. The crude 2,8-dihalogeno derivative prepared was alkalinized with NH3/MeOH and extacted between water-EtOAc. The product crystallizes after partial evaporation of ethylacetate. M.p.123-125° C., yield 88%. MS-ESI(+)m/z 409.5, 411.4, 413.3 [M+H]+
