Vorschrift

To 0.48 g of 1-(2-aminosulfonylphenyl)-5-methyl-1H-tetrazole and 0.52 g of phenyl N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)carbamate in 25 mL of acetonitrile at ambient temperature and pressure was added 0.3 mL of DBU. The mixture was stirred for three hours and then added to 25 g of ice and acidified with hydrochloric acid. The precipitate thus obtained was filtered, washed with water and dried in vacuo to yield 0.65 g of the desired product melting at 207°-209° C. Infrared absorption spectra showed absorption at 1700, 1600 and 1550 cm-1, consistent for the desired structure.
