214.27 mg (0.72 mmol) of chloropyrimidine (Example 6A) are introduced into 28 ml of dry DMSO, 320 mg (1.08 mmol) of 4-amino-2-[(2-aminoethyl)amino]-1,3-thiazole-5-carbonitrile trifluoroacetate (Example 20A) and 742 mg (5.74 mmol) of DIPEA are added, and the mixture is heated at 120° C. under argon for 16 h. Water is added, and the mixture is neutralized with 1N hydrochloric acid and extracted three times with ethyl acetate. The combined organic phases are freed of solvent, and the residue is purified by preparative HPLC. 48.4 mg (14% of theory) of the product are obtained as a solid.
