Reaction Steps

According to the procedure of Example 1, except substituting (E)-(6-{2-[methyl-(1-methyl-1H-indol-2-ylmethyl)carbamoyl]vinyl}-2-oxo-1,4-dihydro-2H-pyrido[2,3-d]pyrimidin-3-yl)acetic acid 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 1-methylpiperazine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (173 mg, 43%) was prepared as a off-white solid: 1H NMR (300 MHz, DMSO-d6) □ 10.78 (br s, 1H), 10.07-10.03 (m, 1H), 8.41-8.37 (m, 1H), 7.98-7.90 (m, 1H), 7.57-7.39 (m, 3H), 7.25-6.99 (m, 3H), 6.42-6.17 (m, 1H), 5.04-4.85 (m, 2H), 4.46-4.03 (m, 5H), 3.72-3.68 (m, 3H), 3.44-3.41 (m, 3H), 3.11-2.91 (m, 7H), 2.78 (s, 3H); MS (ESI) m/e 516 (M+H)+.
