Reaction Steps

According to the procedure of Example 1, except substituting methyl-(1-methyl-1H-indol-2-ylmethyl)amine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, and substituting (E)-3-(4-ethoxycarbonylmethyl-2-oxo-2,3,4,5-tetrahydro-1H-pyrido[2,3-e][1,4]diazepin-7-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, the title compound (0.22 g, 56%) was prepared as a yellow powder and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.53-10.54 (m, 1H), 8.56-8.59 (m, 1H), 8.09-8.16 (m, 1H), 7.28-7.61 (m, 4H), 7.10-7.15 (m, 1H), 6.99-7.04 (m, 1H), 6.19-6.42 (m, 1H), 4.86-5.06 (m, 2H), 4.00-4.14 (m, 5H), 3.62-3.72 (m, 7H), 2.99-3.12 (m, 3H), 1.12-1.20 (m, 3H); MS (ESI) m/e 476 (M+H)+.
