According to the procedure of Example 1 (a), except substituting (E)-3-(3-ethoxycarbonylmethyl-2-oxo-1,2,3,4-tetrahydro-pyrido[2,3-d]pyrimidin-6-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 methyl-(1-methyl-1H-indol-2-ylmethyl)amine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (1.20 g, 89%) was prepared as a tan solid and as a mixture of amide rotomers: 1H NMR (300 MHz, CDCl3) δ 8.34-8.28 (m, 1H), 7.66-7.34 (m, 2H), 7.60-7.53 (m, 2H), 7.33-7.21 (m, 2H), 7.11 (t, J=7.5 Hz, 1H), 6.83 (d, J=15.0 Hz, 1H), 6.50-6.40 (m, 1H), 4.93-4.30 (m, 2H), 4.59-4.52 (m, 2H), 4.27-4.19 (m, 4H), 3.71 (s, 3H), 3.13-3.06 (m, 3H), 1.30 (t, J=7.2 Hz, 3H); MS (ESI) m/e 462 (M+H)+.
