実験手順

To an ice cooled solution containing 5 parts of 2-amino-5-nitrophenol and 9.6 parts of trifluoromethane sulfonic acid in 150 parts of methanol was slowly added 3.9 parts of isoamyl nitrite to complete diazotization. The solution was filtered and the filtrate was poured into 700 parts of ethyl ether. The precipitate was collected, washed with ether and dried under vacuum to give 4.5 parts of product with purity>95%.
