Reaction Steps

183 mg (0.71 mmol) of the 4-chloro-5,7-dimethyl-2-phenylimidazo[5,1-f][1,2,4]triazine (Example 16A) were initially charged in 4 ml of DMSO, and 200 mg (0.85 mmol) of 6-[(2-aminoethyl)-amino]nicotinonitrile (Example 2A) and 1.23 ml (7 mmol) of N,N-diisopropylethylamine were added and the mixture was heated at 150° C. for 12 h. Purification by chromatography on silica gel (mobile phase: dichloromethane/methanol 100:1) gave 10 mg (4% of theory) of the product.
