Versuchsvorschrift
Following Scheme 4, N-tert-butyl-5-iodo-4-(2-(thiophen-3-yl)ethoxy)pyridin-2-amine was cyclized in the presence of palladium (II) acetate and triphenylphosphine to give N-tert-butyl-4,5-dihydropyrido[4,3-b]thieno[2,3-d]oxepin-8-amine (42%). 1H NMR (400 MHz, CDCl3) δ 8.44 (s, 1H), 7.04 (d, J=5.2, 1H), 6.81 (d, J=5.2, 1H), 6.07 (s, 1H), 4.59 (s, 1H), 4.35-4.29 (m, 2H), 3.21-3.07 (m, 2H), 1.42 (s, 9H). MS: (ESI+) 275.1
