实验过程

4-Methyl-5-nitro-pyridin-2-ylamine (1.0 g) was treated with acetic anhydride according to General Procedure Y to give N-(4-Methyl-5-nitro-pyridin-2-yl)-acetamide (1.1 g). LCMS (m/z): 196. N-(4-Methyl-5-nitro-pyridin-2-yl)-acetamide (0.5 g) was reduced under hydrogen atmosphere according to General Procedure Z to give N-(5-Amino-4-methyl-pyridin-2-yl)-acetamide (0.4 g), LCMS (m/z): 166. This was converted to 6-acetylamino-4-methyl-pyridine-3-sulfonyl chloride (0.35 g) according to General Procedure AA. LCMS (m/z): 249.
