実験手順
12 ml of fuming nitric acid (d=1.5) was added dropwise to a solution of 53 g of 2-phenoxycarbonyl-1-naphthol dissolved in 200 ml of chloroform was added dropwise 12 cc of fuming nitric acid (d=1.5) at 10° C. to 30° C. After 30 minutes, the precipitated crystals were filtered, washed well with cooled chloroform to obtain the desired product at a yield of 62%. The product had m.p. of 157° C., and was confirmed by NMR, Mass spectra.
