Procedure

6-Chloro-2-methyl-3-nitro-pyridine (0.5 g) was treated with cyclopropyl-methylamine according to General Procedure U to give methyl-(6-methyl-5-nitro-pyridin-2-yl)-amine. LCMS (m/z): 208. This was reduced under hydrogen atmosphere according to General Procedure Z to give N*2*-cyclopropylmethyl-6-methyl-pyridine-2,5-diamine (0.35 g), LCMS (m/z): 178. This was converted to 6-(cyclopropylmethyl-amino)-2-methyl-pyridine-3-sulfonyl chloride according to General Procedure AA. LCMS (m/z): 261.
