1H-tetrazole in acetonitrile solution (0.45M, 19 mL, 8.5 mmol) was combined with 4-fluoro-nitrobenzene (1 g, 7.09 mmol) in a 40 mL pressure tube, followed by addition of potassium carbonate. The tube was sealed and heated at 110° C. overnight (caution: build-up of pressure possible; use a safety shield). Pressure buildup was observed. The pressure was released carefully. The reaction was concentrated to dryness and diluted with water. The aqueous mixture was extracted 4 times with DCM. The combine organic layers were dried over sodium sulfate, filtered, concentrated and purified by column chromatography through a 40 gram biotage silica gel cartridge eluted with 5-20% ethyl acetate/hexanes (gradient) to give the product as white solid. LRMS talc: 191.0; obs: 192.3 (M+1).
