Reaction Steps

According to the procedure of Example 1, except substituting 2,3-diethoxy-benzyl-methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, and substituting (E)-3-[3-(2-morpholin-4-yl-ethyl)-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, the title compound (0.18 g, 56%) was prepared as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 10.63-10.49 (m, 1H), 10.14-10.12 (m, 1H), 8.41-8.31 (m, 1H), 8.03-7.91 (m, 1H), 7.52-7.45 (m, 1H), 7.38-7.19 (m, 1H), 7.03-6.90 (m, 2H), 6.70-6.51 (m, 1H), 4.63-4.51 (m, 4H), 4.02-3.91 (m, 6H), 3.81-3.68 (m, 4H), 3.60-3.50 (m, 2H), 3.40-3.28 (m, 2H), 3.20-2.85 (m, 5H), 1.40-1.31 (m, 6H); MS (ESI) m/e 524 (M+H)+.
