Reaction Steps

In a similar manner to that described in example 196, from ethyl 1-ethyl-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (60 mg, 0.162 mmol) and (2R)-2-amino-1-propanol (0.05 mL) was prepared 1-ethyl-7-[(4-fluorophenyl)methyl]-4-hydroxy-N-[(1R)-2-hydroxy-1-methylethyl]-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (50 mg, 85% yield) as a white solid after purification by reverse phase HPLC. Analytical data was identical to that described in example 576.
