120 °C

A mixture of 38 parts of 1-fluoro-4-nitrobenzene, 32 parts of 1,4-dihydro-1-propyl-5H-tetrazol-5-one, 14 parts of sodium carbonate and 200 parts of dimethyl sulfoxide was stirred and heated for 4 hours at 120° C. The reaction mixture was cooled and poured into water. The precipitated product was filtered off and crystallized from 2-propanol, yielding 46 parts (74%) of 1,4-dihydro-1-(4-nitrophenyl)-4-propyl-5H-tetrazol-5-one; mp. 91.1° C. (int. 31).
