Reaction Steps

In a similar manner to that described in example 196, from ethyl 7-[(4-fluorophenyl)methyl]-4-hydroxy-1-(3-hydroxypropyl)-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (60 mg, 0.15 mmol) and N-(2-aminoethyl)-N-methylmethanesulfonamide (100 mg, 0.657 mmol) was prepared 7-[(4-fluorophenyl)methyl]-4-hydroxy-1-(3-hydroxypropyl)-N-{2-[methyl(methylsulfonyl)amino]ethyl}-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (18 mg, 24% yield) as a white solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 10.31 (br s, 1 H), 8.58 (s, 1 H), 7.49 (s, 1 H), 7.18-7.14 (m, 2 H), 7.05-6.99 (m, 2 H), 4.37 (m, 2 H), 4.14 (s, 2 H), 3.67 (m, 2 H), 3.51 (m, 2 H), 3.41 (m, 2 H), 2.95 (s, 3 H), 2.83 (s, 3 H), 1.83 (m, 2 H); HRMS m/z calcd for C23H28N4O6FS: 507.1714.
