Reaction Conditions

Reaction Steps

5.0 g of 2-phenyl-6-(2H-tetrazol-5-yl)pyridine was dissolved in 125 ml of dehydrated pyridine. Temperature was elevated to 120° C., and 75 ml was dehydrated by azeotropy. After cooling to 50° C., 3.17 g of benzoyl chloride was added. Temperature was elevated to 100° C., and stirring was conducted for 2 hours under flux. After cooling to room temperature, the reaction solution was poured into 300 ml water, and after adjusting pH to 12 with 20% sodium hydroxide aqueous solution, stirring was conducted for 1 hour. A precipitated yellow solid was taken out by suction filtration, and washed with water. The solid obtained was vacuum dried at 70° C. for 20 hours, and purified with adsorption purification (carrier: NH silica gel, eluting solution: chloroform) to obtain 6.11 g (yield 91%) of PhpyOXDPh. The product was identified with NMR analysis. The result of NMR analysis (CDCl3) was as follows. 8.23-8.26 ppm (3H), 8.14-8.17 ppm (2H), 7.90-7.99 ppm (2H), 7.48-7.58 ppm (6H).
