Participants

Reaction Steps

A solution of 0.5 g of 2,4-bis(5-tetrazolyl)pyridine, 1.6 ml of triethylamine and 0.43 ml of dimethylcarbamoyl chloride in 5 ml of abs. DMF was stirred at room temperature for 24 h, excess dimethylcarbamoyl chloride was decomposed with methanol, and the mixture was then concentrated in vacuo. The result was 1.86 g of an oil which was purified on a silica gel column (40 g) with CH2Cl2 /methanol, gradient 20:1 to 9:1, as eluent. 0.38 g of 10 was obtained, colorless crystals of melting point 150° C.
