Procedure

To a suspension of N-(4-chlorophenyl)-2-[((3-(bromomethyl)benzo[b]thien-2-yl)carbonyl)amino]-5-chlorobenzamide (0.075 g, 0.14 mmol) in methylene chloride (1.5 mL) in a pressure vessel was added dimethylamine hydrochloride (0.035 g, 0.43 mmol), followed by BioRad AG1-X8 anion exchange resin (0.55 g, 0.7 mmol equivalents, OH− form). The vessel was sealed and the mixture was stirred at ambient temperature for 3.5 hours. The vessel was opened and the reaction mixture diluted with methylene chloride (25 mL) and acetonitrile (25 mL), filtered and concentrated in vacuo. Purification by flash chromatography on silica gel, followed by crystallization from acetonitrile afforded 0.030 g (43% yield) of N-(4-chlorophenyl)-2-[((3-(dimethylamino)methylbenzo[b]thien-2-yl)carbonyl)amino]-5-chlorobenzamide, as a crystalline solid; NMR (DMSO-d6/TFA) 13.2 (s, 1),10.7 (s, 1), 7.3-8.1 (m, 11), 3.9 (s, 2), 2.1 (s, 6) ppm.
