To a solution of crude 2-(2-chlorophenyl)-1-(4,5-dihydrobenzo[b]thieno[2,3-d]oxepin-2-yl)-3-(dimethylamino)prop-2-en-1-one (ca. 0.22 mmol) in ethanol (2 mL) was added potassium carbonate (87 mg, 0.63 mmol) and then guanidine hydrochloride (40 mg, 0.42 mmol). The whole was sealed and heated at 90° C. for 8 h, cooled to room temperature and concentrated. The residue was diluted with water and extracted with ethyl acetate. The combined organics were purified by reverse phase HPLC to give 282. MS (ESI) 406.2
