Similarly, a solution of 109 g of 2-chloro-3-nitrobenzoyl chloride in 100 ml of tetrahydrofuran was reacted with a mixture of 103 g of 5-aminotetrazole monohydrate in 1200 ml of hot tetrahydrofuran and 50 ml of water. A voluminous precipitate appeared and, after 1 hour, the mixture was diluted with 2 liters of water and the resulting white solid was collected and oven-dried to give 2-chloro-3-nitro-N-(1H-tetrazol-5-yl)-benzamide melting at about 279° C. with decomposition. In this case, the indicated acid chloride was obtained by the reaction of 2-chloro-3-nitrobenzoic acid with phosphorus pentachloride in cyclohexane. The acid chloride melts at about 57°-59° C.
