Participants

Reaction Steps

In a manner similar to that described in example 316 step 1, from ethyl 7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (160 mg, 0.468 mmol), lithium (bis-trimethylsilyl)amide (0.94 mL of a 1 M solution in tetrahydrofuran, 0.940 mmol), and iodoethane (0.22 mL, 2.81 mmol) was prepared ethyl 1-ethyl-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (170 mg, 95% yield) as a yellow oil. The product was carried on without further purification. 1H NMR (CDCl3) δ 8.37 (s, 1 H), 7.34 (s, 1 H), 7.10-7.05 (m, 2 H), 6.95-6.91 (m, 2 H), 4.39 (m, 2 H), 4.11 (m, 2 H), 4.06 (s, 2 H), 1.35 (m, 3 H), 1.15 (m, 3 H); MS m/z 393 (M+23).
