Procedure
2-chloro-5-nitropyrimidine (1.6 g, 10 mmol), 1H-tetrazole (24.44 mL, 11 mmol, 0.45M in MeCN) were added in DMF (20 mL), cooled to 0° C., then triethylamine (1.67 mL, 12 mmol) was added drop-wise. After 15 minutes, water (100 mL) was added, extracted with ethyl acetate (100 mL×1, 50 mL×6). The organic phase were combined and dried by magnesium sulfate, filtered, concentrated and purified by column chromatography through a 100 gram Biotage SNAP KP-Sil™silica gel cartridge eluting with 30% ethyl acetate/hexanes to give the title compound as a pale yellow solid.
