Procedimiento

To N-isopropyl-2,2-dimethyl-3-oxo-N-[(3R)-piperidin-3-yl]-4-[2-(propionylamino)ethyl]-7-(trifluoromethyl)-3,4-dihydro-2H-1,4-benzoxazine-6-carboxamide hydrochloride (300 mg) were added N-Boc valine (158 mg), WSC (210 mg), HOBt (150 mg), triethylamine (0.30 ml) and chloroform (5 ml), and the mixture was stirred at room temperature overnight. After the reaction is completed, the solvent was concentrated, and the obtained residue was purified by column chromatography (hexane:ethyl acetate=1:2) to give the desired title compound (440 mg) as white amorphous.
