Reaction Steps
1-(4-Hydroxyphenyl)-1,3-heptandione, 1121 g, is dissolved in 4070 g acetic acid. O-(4-Nitrophenyl)hydroxylamine, 784 g, is added in portions keeping the temperature at ca 20° C. The formed slurry is stirred for 3 h, cooled to 15° C., filtered and washed with 1590 g acetic acid. 1944 g wet cake corresponding to 1596 g dry 1-(4-hydroxyphenyl)heptane-1,3-dione-3-[O-(4-nitrophenyl)oxime] is obtained. Yield 88%.
