Reaction Steps

The title compound was prepared in analogy to the synthesis of 4-(5-cyanomethoxy-pyrimidin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (intermediate C32/step 1) from 4-(5-hydroxy-pyrimidin-2-ylamino)-piperidine-1-carboxylic acid tert-butyl ester (intermediate C31/step 2) by reaction with rac-toluene-4-sulfonic acid 2,2-dimethyl-[1,3]dioxolan-4-ylmethyl ester (commercially available) and potassium carbonate in DMF at rt for 48 h, followed by BOC and isopropylidene cleavage with 4 M HCl in dioxane and ethanol at 60° C. in analogy to the procedure described for 2-[4-methoxy-6-(piperidin-4-ylamino)-[1,3,5]triazin-2-ylamino]-ethanol (intermediate C26/step 3) and subsequent ion exchange chromatography on Q-Sepharose Fast Flow. MS (ISP): 269.1 [M+H]+.
