Reaction Steps

According to the procedure of Example 1 (a), except substituting 2,3-dimethylbenzylmethyl amine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, and substituting (E)-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3yl)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 (0.368 g, 75%) was prepared as an off-white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.68-10.64 (m, 1H), 8.38-8.32 (m, 1H), 8.10-7.99 (m, 1H), 7.57-7.50 (m, 1H), 7.29-7.04 (m, 3H), 6.94-6.77 (m, 1H), 4.82-4.65 (m, 2H), 3.06-2.85 (m, 5H), 2.57-2.48 (m 2H), 2.28-2.14 (m, 6H); MS (APCI) m/e 350 (M+H)+.
