Procedure
2,3-Difluoro-5-iodo-N,N-dimethyl-benzamide (507, 1.63 mmol), 4-(aminomethyl)-pyridine (1.8 ml, 17.73 mmol), di-iso-propylethylamine (0.31 ml, 1.78 mmol), and dioxane (3 ml) were combined and stirred for 18 hours at 75° C. The reaction mixture was concentrated in vacuo to give approximately 650 mg of crude 3-fluoro-5-iodo-N,N-dimethyl-2-[(pyridin-4-ylmethyl)-amino]-benzamide, which was used directly in the next step. MS: m/z 400.2 (M+H+).
