According to the procedure of Example 1, except substituting (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)acrylic acid hydrochloride for the (E)-3-(4-methyl-2-oxo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepin-7-yl)acrylic acid hydrochloride, and substituting (2-ethoxy-3-methoxy-benzyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (429 mg, 88%) was prepared as an off-white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.6 (s, 1H), 8.34 (d, J=13.2 Hz, 1H), 8.08-8.01 (m, 1H), 7.50 (dd, J=9.2, 2.0 Hz, 1H), 7.25 (dd, J=9.3, 5.5 Hz, 1H), 7.06-6.94 (m, 2H), 6.67 (dd, J=11.4, 4.7 Hz, 1H), 4.91 (br s, 1H), 4.78-4.64 (m, 2H), 4.02-3.95 (m, 2H), 3.79 (s, 3H), 3.09-2.86 (m, 5H), 2.55-2.49 (m, 2H), 1.30-1.26 (m, 3H); MS (ESI) m/e 396 (M+H)+.
