Versuchsvorschrift

To a mixture of 3-(8-bromo-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamido)-4-chlorobenzoic acid (2.5 g, 5.07 mmol) in THF (50 mL) was added EDCI (1.94 g, 10.14 mmol), HOBt (1.03 g, 7.61 mmol), DIPEA (5 mL) and 3-hydroxyazetidine hydrochloride (0.83 g, 7.61 mmol) by sequence under nitrogen atmosphere at room temperature. The reaction mixture was stirred overnight, diluted with water, extracted with EtOAc. The organic layer was dried over Na2SO4, concentrated in vacuo. The crude product was purified by flash column chromatography on silica gel (eluted by hexanes:EtOAc=1:2) to give 8-bromo-N-(2-chloro-5-(3-hydroxyazetidine-1-carbonyl)phenyl)-N-methyl-4,5-dihydrobenzo[b]thieno[2,3-d]oxepine-2-carboxamide (1.6 g, yield 58%). LC-MS: (ESI, m/z)=547 [M+H]+
