Procedure

A microwave reaction vessel is charged with (S)-pyrrolidine-2-carboxylic acid (5-tert-butyl-isoxazol-3-yl)-amide; hydrochloride, 3-chloro-2-fluoro-5-trifluoromethylpyridine, triethylamine and ethanol. The mixture is heated in a microwave reactor at 175° C. for 1 h, maintaining the watts at 60 to keep the reactor from shutting down. The reaction is cooled to room temperature and concentrated in vacuo to afford an oil which is purified by reverse phase preparative HPLC. Product fractions are combined and concentrated in vacuo to afford title compound (64.4 mg). ESI m/z 417 [M+H]+.
