実験手順

1.9 g (10 mmol) of 2,6-dichloro-purine are stirred in 40 ml of DMF/n-butanol (1:3) with 4.1 g (30 mmol) of 4-nitro-aniline at 130° C. for 24 h and the crystal mass which precipitates out on cooling is filtered off and dried in vacuo. 2-Chloro-6-(4-nitro-phenyl-amino)-purine is obtained; m.p.>270° C.; FAB-MS: (M+H)+=291; Rf=0.6 (CH2Cl2:methanol=9:1).
