Procedimiento

To a solution of 6-[(2R,6S)-2,6-dimethylmorpholin-4-yl]-7-fluoro-3-[4-(morpholin-4-ylcarbonyl)-1,3-thiazol-2-yl]-1,2-benzoxazole-5-carbaldehyde (Intermediate 389, 90 mg, 0.19 mmol) in IPA was added barbituric acid (24 mg, 0.103 mmol) and the mixture heated at 85° C. for 16 hours. Solvents were evaporated and the residue was purified by reverse phase HPLC to give product as solid (as a TFA salt). Yield: 16 mg (14%).
