N-methyl(3-methylbenzo[b]thiophen-2-yl)methanamine → (E)-3-[6-Amino-5-(4-methyl-piperazin-1-ylmethyl)pyridin-3-yl]-N-methyl-N-(3-methyl-benzo[b]thiophen-2-ylmethyl)acrylamide hydrochloride

Reaction Steps

According to the procedure of Example 1, except substituting (E)-3-[6-amino-5-(4-methyl-piperazin-1-ylmethyl)pyridin-3-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 (101 mg, 46%) was prepared as a light, yellow powder and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.6 (br s, 1H), 8.27 (s, 1H), 8.16 (s, 1H), 7.87 (d, J=7.6 Hz, 1H), 7.73 (d, J=7.1 Hz, 1H), 7.52-7.28 (m, 5H), 7.11 (d, J=15.3 Hz, 1H), 5.11-4.89 (m, 2H), 3.55 (br s, 2H), 3.37-3.23 (m, 4H), 3.14 (s, 2H), 3.10-2.92 (m, 5H), 2.72 (s, 3H), 2.42 (s, 3H); MS (ESI) m/e 450 (M+H)+.
