実験手順
A mixture of 12 grams (37.1 mmol, 1.0 eq) of 2-methoxy-4-(phenylamino)benzenediazonium hydrogen sulfate (TCI America, Portland, Org.) in 600 mL of water was heated to 35°-40° C. and then filtered. To the filtrate was added a solution of 9.6 grams (52.0 mmol, 1.4 eq) of potassium hexafluorophosphate in 220 mL of water and a precipitate formed immediately. The mixture was stirred for 2 hours and collected by filtration, washed with water and then with approximately 100 mL of isopropanol and air dried to give 12.05 grams (87.5% yield) of 2-methoxy-4-phenylaminobenzenediazonium hexafluorophosphate.
