(2-Propoxy-3-methoxy-benzyl)methylamine → (E)-N-(3-Methoxy-2-propoxy-benzyl)-N-methyl-3-(7-oxo-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)acrylamide hydrochloride

Participants

Reaction Steps

According to the procedure of Example 1, except 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, and substituting (3-methoxy-2-propoxy-benzyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (193 mg, 22%) was prepared as a white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.6 (s, 1H), 8.35 (d, J=14.1 Hz, 1H), 8.09-8.01 (m, 1H), 7.50 (dd, J=15.2, 2.5 Hz, 1H), 7.24 (d, J=15.3 Hz, 1H), 7.07-6.94 (m, 2H), 6.67-6.62 (m, 1H), 5.43 (br s, 1H), 4.79-4.64 (m, 2H), 3.87 (q, J=6.9 Hz, 2H), 3.79 (s, 3H), 3.10-2.86 (m, 5H), 2.56-2.45 (m, 2H), 1.71 (app sextet, J=7.1 Hz, 2H), 0.97 (q, J=7.3 Hz, 3H); MS (ESI) m/e 410 (M+H)+.
