Reaction Steps

According to the procedure of Example 1 (a), except substituting (2,3-dimethoxy-benzyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, and substituting (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-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 (0.362 g, 61%) was prepared as an orange solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.67-10.64 (m, 1H), 8.36-8.32 (m, 1H), 8.09-8.02 (m, 1H), 7.52-7.47 (m, 1H), 7.31-7.22 (m, 1H), 7.08-6.95 (m, 2H), 6.69-6.64 (m, 1H), 4.78-4.62 (m, 2H), 3.80 (s, 3H), 3.73 (s, 3H), 3.01-2.85 (m, 5H), 2.56-2.49 (m, 2H); MS (ESI) m/e 382 (M+H)+.
