Dimethylformamide → 2-Chloro-6-(3-trifluoromethyl-phenyl-amino)-purine

Participants

Reaction Steps

1.9 g (10 mmol) of 2,6-dichloro-purine are stirred in 60 ml of butanol and 3 ml of DMF with 8.05 g (50 mmol) of 3-amino-benzotrifluoride at 60° C. for 3 h. On cooling, 2-chloro-6-(3-trifluoromethyl-phenyl-amino)-purine is obtained as a crystalline mass. This is filtered off and dried in vacuo; m.p. 248° C.; FAB-MS: (M+H)+=314; Rf=0.45 (CH2Cl2:methanol=95:5).
