実験手順

According to the procedure of Example 35g, (methyl-(1-methyl-1H-indol-5-ylmethyl)-amine (155 mg, 0.89 mmol) and (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3yl)acrylic acid hydrochloride (229 mg, 0.90 mmol), were coupled to give crude product. Purification by column chromatography (silica gel, 5% MeOH/CH2Cl2) gave the title compound (217 mg, 65%) as a red solid and a mixture of amide rotomers: 1H NMR (400 MHz, DMSO-d6) δ 10.63-10.62 (m, 1H), 8.36-8.33 (m, 1H), 8.06 (s, 1H), 7.56-7.51 (m, 1H), 7.43-7.19 (m, 4H), 7.08-7.01 (m, 1H), 6.38 (s, 1H), 4.85-4.67 (m, 2H), 3.76 (s, 3H), 3.06-2.85 (m, 5H), 2.54-2.52 (m, 2H); ESI MS m/z 375 [C22H22N4O2+H]+.
