3,4-Dimethyl-2-(methylaminomethyl)thieno[2,3-b]thiophene → (E)-3-(6-Amino-5-morpholin-4-ylmethyl-pyridin-3-yl)-N-(3,4-dimethyl-thieno[2,3-b]thiophen-2-ylmethyl)-N-methyl-acrylamide hydrochloride

Participants

Reaction Steps

According the procedure of Example 1, except substituting (E)-3-(6-amino-5-morpholin-4-ylmethyl-pyridin-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 (3,4-dimethyl-thieno[2,3-b]thiophen-2-ylmethyl)methylamine for the methyl-(1-propyl-naphthalen-2-ylmethyl)amine, the title compound was prepared (70 mg, 13%) as a light, yellow powder and as a mixture of amide rotamers: 1H NMR (300 MHz, DMSO-d6) δ 8.63 (s, 1H), 8.40 (s, 1H), 7.51 (d, J=15.1 Hz, 1H), 7.20-7.12 (m 2H), 5.00-4.77 (m, 2H), 4.40-4.32 (m, 2H), 3.95-3.15 (m, 10H), 3.13 (s, 3H), 2.90 (s, 1H), 2.46 (s, 3H), 2.45 (s, 3H); MS (ESI) m/e 457 (M+H)+.
