실험 절차

To a warm ethanol solution containing 5.8 g. (0.01 mol) of the dibromopyrazolone (Compound 2-A) are added 2.4 g. (0.011 mol) of 4-amino-2,6-dichlorophenol hydrochloride. After this has dissolved, 3.3 g. of triethylamine are added. The solution, which quickly becomes magenta, is stirred for 15 minutes and cooled in an ice-acetone bath. The solid recovered is the dye IV with traces of impurity; m.p. 215°-217° C. (dec.). ##SPC4##
