Syntheses for 3-(1H-tetrazol-5-yl)-4(3H)-quinazolinone sodium salt monohydrate (9; MDL 427) and the related formamido compound, 2-(formylamino)-N-1H-tetrazol-5-ylbenzamide (10), are described. Both compounds are active in the rat passive cutaneous anaphylaxis and passive peritoneal anaphylaxis tests. A 94:6 equilibrium mixture of 9 and ionized 10, respectively, forms in aqueous buffer systems at a
