Procedure
[2-Methyl-6-(1H-tetrazol-1-yl)pyridin-3-yl]acetic acid was prepared from 5-chloro-6-methylpyridin-2-amine in six steps in an analogous fashion to that described for the synthesis of [6-(1H-tetrazol-1-yl)pyridin-3-yl]acetic acid (Method 1, Steps A-F). LC-MS (IE, m/z): 192 [M+1-N2]+, 220 [M+1]+. 1H-NMR (400 MHz, CDCl3) δ 9.88 (s, 1H), 7.9 (d, 1H), 7.85 (d, 1H), 3.79 (s, 2H), 2.59 (s, 3H).
