Versuchsvorschrift
A solution of 2-(methyl(tetrahydro-2H-pyran-2-yl)amino)thiazole-5-carbaldehyde (250 mg, 1.10 mmol) and 2-aminothiazole (110 mg, 1.10 mmol) in toluene (11 mL) and molecular sieves 3 Å were stirred at reflux overnight. The strongly yellow solution of the corresponding imine was then poured over NaBH4 (212 mg, 5.61 mmol) in hot EtOH (80 mL). The colorless solution was filtered, concentrated and purified by column chromatography yielding N-methyl-N-(tetrahydro-2H-pyran-2-yl)-5-((thiazol-2-ylamino)methyl)thiazol-2-amine (50 mg, 17%) as a solid.
