1-Adamantanecarbonyl chloride → HCID 13559530, compound

Participants

Reaction Steps

To a solution containing 1.4 g of 5-phenyltetrazolo[1,5-a][1,2,4]triazolo[1,5-c]pyrimidine-6-ethanol (0.005 mole) dissolved in 12 ml of pyridine is added 1.0 g of 1-adamantanecarbonyl chloride (0.005 mole). The reaction mixture is stirred for one hour and then allowed to stand overnight at room temperature. The reaction mixture is evaporated to dryness yielding a residue. The residue is taken up in methylene chloride, extracted with water, dried over sodium sulfate and evaporated to dryness yielding a crude product. The crude product is chromatographed on silica gel to yield 2-(5-phenyltetrazolo[1,5-a][1,2,4]triazolo[1,5-c]pyrimidin-6-yl)ethyl tricyclo[3.3.1.13,7 ]decane-1-carboxylate having the structural formula ##STR25## and the azido tautomer thereof as a white solid having a melting point of 129°-130° C. and the following elemental analysis:
