実験手順
Example 89A is prepared in analogy to Example 48A from 4-amino-2-(methylsulphonyl)-1,3-thiazole-5-carbonitrile (Example 18A) (499 mg, 2.45 mmol) and 2-aminoethanol (300 mg, 4.91 mmol) in DMSO (80° C., 20 h). Removal of the solvent results in a crude product 527 mg (50% of theory) which is employed without further purification.
