Participants

Reaction Steps

According to the procedure of Example 1, except substituting methyl-(3-methyl-benzo[b]thiophen-2-ylmethyl)amine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, and substituting (E)-3-(6-amino-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, the title compound (2.2 g, 73%) was prepared as a yellow solid: 1H NMR (300 MHz, DMSO-d6) 8.21 (s, 1H), 2.81-2.75 (m, 1H), 2.71-2.59 (m, 3H), 7.41-7.25 (m, 2H), 6.85-6.65 (m, 1H), 6.50-6.41 (m, 1H), 5.01-4.81 (m, 2H), 4.78-4.61 (m, 2H), 3.12 (s, 3H), 2.41 (s, 3H); MS (ESI) m/e 338 (M+H)+.
