الإجراء التجريبي

Analogously to Example 1, 308 mg (1.0 mmol) of 2-chloro-6-(3-chloro-phenyl-amino)-9-ethyl-9H-purine [described in Stage 1.2] and 324 mg (3 mmol) of 1,2-phenylenediamine are reacted in 10 ml of n-butanol in a glass pressure reactor for 19 h at 140° C., followed by addition of 486 mg (4.5 mmol) of 1,2-phenylenediamine and further reaction at 135° C. for 17 h. After purification by means of column chromatography, 2-[2-amino-phenyl-amino]-6-(3-chloro-phenyl-amino)-9-ethyl-9H-purine is obtained; FAB-MS: (M+H)+=380; HPLC: tret (grad20/2)=11.36 minutes.
