実験手順
According to the procedure of Example 35g (3,4-dihydro-2H-benzo[b][1,4]dioxepin-6-ylmethyl)-methyl-amine (239 mg, 1.24 mmol) and (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)acrylic acid hydrochloride (318 mg, 1.25 mmol), were coupled to give crude product. Purification by column chromatography (silica gel, 5% MeOH/CH2Cl2) gave the title compound (385 mg, 79%) as a yellow solid and a mixture of amide rotomers: 1H NMR (400 MHz, DMSO-d6) δ 10.66-10.63 (m, 1H), 8.36-8.32 (m, 1H), 8.07-8.03 (m, 1H), 7.51-7.46 (m, 1H), 7.30-721 (m, 1H), 6.93-6.88 (m, 2H), 6.78-6.76 (m, 1H), 4.76-4.59 (m, 2H), 4.13-4.06 (m, 4H), 3.11-2.84 (m, 5H), 2.54-2.52 (m, 2H), 2.11-2.07 (m, 2H); ESI MS m/e 394 [C22H23N3O4+H]+.
