Reaction Steps

The title compound was prepared in analogy to example 57 from 19 mg (0.19 mmol) cyclohexylamine and 65 mg (0.21 mmol) 2-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenylamino]-thiazole-5-carbaldehyde using a solvent mixture of tetrahydrofurane (1 ml), methanol (1 ml) and methylene chloride (1 ml). The reaction was not complete and the same amount of reagent was added like in example 57. Only the imine was formed. Therefore the crude product was dissolved in methanol (1 ml) and 8.6 mg sodium borohydride was added and the reaction stirred for 4 hours at room temperature. After workup the crude product was purified on silica gel with methylene chloride/methanol 9/1 yielding 16 mg (21%) of (5-cyclohexylaminomethyl-thiazol-2-yl)-[3-methoxy-4-(4-methyl-imidazol-1-yl)-phenyl]-amine as a yellow oil.
