Reaction Steps

According to the procedure of Example 1, except 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, and substituting (2-ethoxy-3-methoxy-benzyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (155 mg, 37%) was prepared as a off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 10.15-10.13 (m, 2H), 8.40-8.35 (m, 1H), 8.00-7.92 (m, 1H), 7.54-7.42 (m, 1H), 7.25-7.20 (m, 1H), 7.13-6.68 (m, 2H), 6.66-6.61 (m, 1H), 5.11 (br s, 1H), 4.78-4.63 (m, 2H), 4.57-4.52 (m, 2H), 4.01-3.95 (m, 4H), 3.82-3.58 (m, 9H), 3.37-3.35 (m, 2H), 3.20-2.86 (m, 5H), 1.28-1.18 (m, 3H); MS (ESI) m/e 510 (M+H)+.
