실험 절차

(S)-tert-Butyl 4-(1-cyano-2-(4-(2-oxo-2,3-dihydrobenzo[d]oxazol-5-yl)phenyl)ethylcarbamoyl)tetrahydro-2H-pyran-4-ylcarbamate (Example 33, step (ii), 160 mg) was heated at 50° C. in formic acid (0.5 mL) for 10 min. The cooled solution was diluted with water (50 mL) and basified with ‘880’ ammonia and the resulting precipitate extracted into ethyl acetate (200 mL). The dried extract was concentrated to dryness and purified purified by reversed phase HPLC (using a SunFire column) eluting with methanol/0.1% aqueous trifluoroacetic acid. The pure fractions were freeze dried to afford the titled compound as a trifluoroacetatic acid salt (36 mg) TFA salt as a colourless solid.
