Procedure

The preparation of 5-(2-chloro-5,6-dimethyl-3-nitropyridin-4-ylamino)pentan-1-ol was described in Part A of Example 85. Under a nitrogen atmosphere, cerium (III) chloride heptahydrate (8.08 g, 21.7 mmol) and sodium azide (5.64 g, 86.8 mmol) were added to a solution of 5-(2-chloro-5,6-dimethyl-3-nitropyridin-4-ylamino)pentan-1-ol (12.48 g, 43.38 mmol) in a 9:1 mixture of acetonitrile and water (145 mL). The reaction was stirred and heated at reflux for two days then allowed to cool to room temperature. A precipitate was removed by filtration and washed with acetonitrile. The filtrate was concentrated under reduced pressure to provide 12.13 g of 5-[(5,6-dimethyl-8-nitrotetrazolo[1,5-a]pyridin-7-yl)amino]pentan-1-ol as a yellow solid.
