Reaction Steps

3-(1-Chloro-2,2-difluoro-propylideneamino)-5-(5-methyl-pyridin-2-yl)-benzoic acid methyl ester (0.611 g, 1.732 mmol) and NaN3 (0.225 g, 3.464 mmol) were added to 10 mL acetonitrile, and the mixture was stirred at room temperature for 90 minutes. Solvent was removed under reduced pressure and the residue was partitioned between water and EtOAc. The combined organic layers were washed with water, dried (MgSO4), filtered and concentrated under reduced pressure to give 0.605 g of 3-[5-(1,1-Difluoro-ethyl)-tetrazol-1-yl]-5-(5-methyl-pyridin-2-yl)-benzoic acid methyl ester as a white powder, MS (M+H)=360.
