Procedure

Crude 1-(8-bromo-4,5-dihydrobenzo[b]thieno[2,3-d]oxepin-2-yl)-2-(2-chlorophenyl)-3-(dimethylamino)prop-2-en-1-one was suspended in methanol (5 mL) and treated with hydrazine (ca. 1 mL). After 2 h, the mixture was concentrated and the residue purified by flash column chromatography to give 276 as colorless solid (527 mg). MS (ESI): 459.0
