Versuchsvorschrift

9-Bromo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carboxylic acid (3.2 g, 10.4 mmol), methyl N-Boc-carbamimidothioate (4.7 g, 12.4 mmol), HATU (5.0 g, 26.0 mmol) and DIPEA (6.7 g, 52.1 mmol) were dissolved in DCM (200 mL). After the resulting mixture was stirred at room temperature for 2 h, the reaction mixture was concentrated and methanol (50 mL) was added and filtered. The solid was collected to give methyl N′-9-bromo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-2-carbonyl-N-Boc-carbamimidothioate (3.0 g, 60%). 1H NMR (DMSO, 400 MHz) δ 12.84 (s, 1H), 8.31 (s, 1H), 8.18 (s, 1H), 7.32-7.27 (m, 2H), 5.72 (s, 1H), 4.49 (s, 4H), 2.30 (s, 3H), 1.49 (s, 9H)
