Procedimiento

The mixture 85.6 mg of 7-benzylamino-5-chloro-3-isopropylpyrazolo[4,3-d]pyrimidine XVI, 0.21 mL of heptyl amine and 1 mL of pentanol was heated at 125° C. for 12 hours. The reaction mixture was evaporated to dryness in vacuo and then chromatographed on silica gel. The mixture of chloroform/acetone/heptane (1:1:1) was used as a mobile phase.
