In a similar manner to that described in Paragraph A above, N-(4-chlorophenyl)-2-[((5-(bromomethyl)-3-chlorothiophen-2-yl)carbonyl)amino]-5-chlorobenzamide (0.5 g, 1.0 mmol) was reacted with thiomorpholine (0.5 mL, 4.8 mmol). Purification by flash chromatography on silica gel afforded 0.4 g (73% yeild) of N-(4-chlorophenyl)-2-[((5-((thiomorpholin-4-yl)methyl)-3-chlorothiophen-2-yl)carbonyl)amino]-5-chlorobenzamide; as a pale yellow powder; NMR (CDCl3) 11.0 (s, 1), 9.0 (s, 1), 8.2 (d, 1), 7.8 (d, 2), 7.5 (d, 1), 7.4 (d, 2), 7.4 (s, 1), 7.2 (dd, 1), 3.7 (s, 2), 2.8 (m, 4), 2.7 (m, 4) ppm.
