Participants

Reaction Steps

According to the procedure of Example 1 (a), except substituting ((1H-benzo[d]imidazol-5-yl)-N-methylmethanamine) 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. Purification by preparative HPLC (water/acetonitrile/0.05% TFA mixture) gave the title compound ((E)-N-((1H-benzo[d]imidazol-5-yl)methyl)-N-methyl-3-(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-3-yl)acrylamide) (143 mg, 37%) as a white solid and a mixture of amide rotomers: 1H NMR (400 MHz, DMSO-d6) δ 10.60 (m, 1H), 8.36 (m, 1H), 8.21 (s, 1H), 8.07 (s, 1H), 7.59-7.21 (m, 4H), 7.12-7.08 (m, 1H), 4.91-4.72 (m, 2H), 3.10-2.86 (m, 5H), 2.55-2.49 (m, 2H); ESI MS m/z 362 [C20H19N5O2+H]+.
