Ethyl 1-(aminomethyl)cyclohexane-1-carboxylate → 1-{[6-(2-Methylcarbamoyl-pyridin-4-yloxy)-benzooxazol-2-ylamino]methyl}-cyclohexanecarboxylic acid ethyl ester

Participants

Reaction Steps

To a solution of 1-aminomethyl-cyclohexanecarboxylic acid ethyl ester in THF was added 4-(2-methanesulfinyl-benzooxazol-6-yloxy)-pyridine-2-carboxylic acid methylamide from Step 3 of Example 2. After reacting at room temperature for 2 hours the solvent was removed and the crude product was diluted with ethyl acetate and some dichloromethane, then washed three times with brine, dried with anhydrous sodium sulfate, filtered and concentrated. The final product was purified by reverse phase preparatory HPLC. MH+=453.1.
