2-{[7-(2,4-Dichlorophenyl)imidazo[1,2-c]pyrimidin-5-yl]amino}ethanol (Example 49A) is prepared in analogy to Example 36A from 5-chloro-7-(2,4-dichlorophenyl)imidazo[1,2-c]-pyrimidine (Example 6A) (200 mg, 0.7 mmol) and 2-aminoethanol (82 mg, 1.3 mmol) in DMSO (80° C., 4 h). Removal of the solvent results in a crude product which is precipitated from dichloromethane. The product is filtered off with suction and dried. 216 mg (99% of theory) of product are obtained as a solid.
