(2-Isopropoxy-3-methoxy-benzyl)methylamine → (E)-N-(2-Isopropoxy-3-methoxy-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 (2-isopropoxy-3-methoxy-benzyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound (326 mg, 83%) was prepared as a white solid and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 10.6 (s, 1H), 8.36 (d, J=17.3 Hz, 1H), 8.10-7.98 (m, 1H), 7.50 (d, J=15.3 Hz, 1H), 7.28-7.17 (m, 1H), 7.05-6.93 (m, 2H), 6.63 (dd, J=7.3, 7.3 Hz, 1H), 5.77 (br s, 1H), 4.77-4.63 (m, 2H), 4.59-4.45 (m, 1H), 3.79 (s, 3H), 3.08-2.81 (m, 5H), 2.56-2.44 (m, 2H), 1.23 (t, J=5.7 Hz, 6H);
