Reaction Steps
To a solution of N-BOC-piperazine (300 mg) in MeCN (5 mL) was added potassium carbonate (289 mg) followed by methanesulfonic acid 5-methyl-isoxazol-3-ylmethyl ester (369 mg). The reaction mixture was heated to reflux for 24 h. After cooling the reaction mixture was diluted with water extracted into ethyl acetate, dried (MgSO4) and the solvent was removed in vacuo to yield 4-(5-methyl-isoxazol-3-ylmethyl)-piperazine-1-carboxylic acid tert-butyl ester (404 mg).
