N-methyl(3-methylbenzo[b]thiophen-2-yl)methanamine → (E)-N-Methyl-N-(3-methyl-benzo[b]thiophen-2-ylmethyl)-3-[3-(2-morpholin-4-yl-ethyl)-2-oxo-1,2,3,4-tetrahydro-pyrido[2,3-d]pyrimidin-6-yl]acrylamide hydrochloride

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 methyl-(3-methyl-benzo[b]thiophen-2-ylmethyl)amine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (140 mg, 33%) was prepared as a off-white solid: 1H NMR (300 MHz, DMSO-d6) δ 10.45 (br s, 1H), 10.14 (s, 1H), 8.41-8.39 (m, 1H), 8.01 (s, 1H), 7.88-7.86 (m, 1H), 7.74-7.73 (m, 1H), 7.56-7.53 (m, 1H), 7.41-7.18 (m, 3H), 6.31 (br s, 1H), 5.11-4.88 (m, 2H), 4.57-4.55 (m, 2H), 3.99-3.96 (m, 2H), 3.75-3.71 (m, 4H), 3.57-3.55 (m, 2H), 3.39-3.37 (m, 2H), 3.15-2.94 (m, 5H), 2.42 (s, 3H); MS (ESI) m/e 506 (M+H)+.
